Diana/Original Model-6 stripdown.

 

With thanks to Chuck for the scans of stripdown articles by the great Dennis Commins and to George for his excellent tips arising from experience with stripping a model 6:

 

 

George's tips:

This is some pointers and advice to those that will rebuild / re seal their Giss (model 6) system pistols at some time. I have just resealed mine and thought it would be a good idea to write up things that you need to be careful of and how to do it right and not damage yourself or the pistol. Here are my thoughts:
• Chambers have the parts / seals etc.
• There are stage by stage rebuild instructions on the net read them all.
• It is not difficult but because it is a well-made piece of kit you need to raise your game when working on it.
• The threads are fine – think clock makers threads.
• Two of the screws could be from a clock and they are easy to loose or damage.
• The rear cylinder cap can be very tight, mine was. The gun was wrapped with a leather welding gauntlet to protect it from the vice yaws but it kept moving. So I used new fibre vice guards on their own , these gripped and did not marks the pistol, these will now go away and only be used for this type of work. I used a leather strap wrench, small chain wrench with leather to protect but to no avail. I used water pump pliers VERY big ones and I mean big, they will open up to 200mm and are big enough to grip the gas suspension balls on Citrioen cars. They are not stilsons! With leather to protect the cap it finally moved, it did not leave a mark.
• The lock screw hole was drilled after it was all assembled so it will have to go to this mark when the end cap goes back on.
• The two little screws that lock the cog bearings holders were also drilled after assembly so must go back on the same side as they come off, mark one with tape and the side of the gun with tape it came from. Use jewellers screw drivers to undo the little screws – do not buy a cheap pound-land set, get some real ones.
• There is one spring that can fly if you are not careful, wear safety glasses and cover it with a cloth when you remove it - it’s the one that holds the bear’s claw I place.
• The trigger has to be removed - easy pin out job, but there is a hair spring on the trigger make sure you take note of how it is fitted before you withdraw the trigger as it could become dislodged.
• I did not remove the barrel – support the cocking mechanism parts as you drift out the pin as it is an interference fit.
• I made up a tool – square taper steel rod fitted into a large file handle, you could use a tang of a file with a cloth around it but do yourself a favour do it right make the tool or a simple spring compressor – this is used to compress the spring and align the rear dummy piston – details are in over haul instructions found on web. Now I have done it without a spring compressor using this tool, I will be making up a simple compressor to help me in the future, as it is a bit of a fiddle / struggle to use this simple tool to replace the cogs on reassembly. Especially as you have lots of newly greased parts and if you drop them you will probably need to degrease them to get the grit off and start over.
• You need to compress the spring by pushing on the rear dummy piston with the tool as you remove the cog bearing caps, the caps will be tight – leather and pliers will work. The caps will probably come away leaving the cogs behind. Fish them out and they should go back in the same side the same was round as they will have warn to match the rack they run on. Put them on a piece of wire that is marked at one end so it correlates with the pistol side and cap that has been marked.
• First de-gunk all parts with white spirit using quality “J” cloths to keep paper towel fibres and lint out of your chamber. Use a dowel rod with a slot cut in it and fit squares of cloth in it to reach right inside the chamber. Dry using new pieces of cloth. Go and de-gunk the springs, pistons, caps and cogs while the chamber dries a bit. Now using a new dowel clean the chamber using acetone.
• Allow to dry, then mix up some graphite powder with acetone and dribble into the chamber – I used a plastic pipette. Allow to dry and then using the dowel rod and a clean cloth burnish the inside of the chamber.
• Remove old washers with a screw driver. The new washers are quite hard material and you could mangle them putting them on. I made a mandrel from some nylon rod turned in the lathe to 12.5 mm then a taper of 7 degrees to allow the seals to slide up and stretch slowly then pushed over the button while the piston is gently held in the vice. The nylon was lubricated with a smidgeon of silicone oil. The button has an OD of 12.2mm on my pistol. Get yourself a set of electric verniers they can now be bought for under £20 and you will use them for all sorts of stuff.
• I lubricated my seal using knox grease and the rest of the gubbins with abby gun moly.
• Putting the front piston in make sure it is the right way up with the runners lining up with the slits in the chamber. Ease the new seal with a blunt screwdriver past all the naughty bits that will try and destroy your good work.
• Spring in, then rear cylinder, now the only real difficult bit, Compress the spring so the cylinder goes in no more than 1.5mm and put in the gear caps with the cogs stuck on them with grease, use no force slightly turn the rear cylinder to get it to go in – first one easy not so the second one. As one write up says it can take 2mins or two hours took me about 5 mins. But you have to keep that compression on and it is this reason I’m making a compressor for next time as you cannot really see what is going on, and it is a bit hit and miss.
• You must now line up the holes to put in the locking screws for the bearing caps and the end cap, use a solid wire (gas welding rod) or a jewellers screw driver to feel when the inner and outer hole align – now you did put the caps on the right side didn’t you! Put a cloth under the gun as you WILL drop the screws and you WILL not see them again. Glue the cap screws to the driver with a blob of grease if it helps and remember FINE threads cross easily. Drive them in with the driver with your fingertips till they stop. If they are too proud the hole alignment is not perfect so keep gentle pressure on the screw and turn the cap slowly back and forward feeling the screw slowly in. For the cylinder cap I found a piece of solid wire the same dia. as the hole and used that to align the two parts but I still needed a little adjustment when the screw was driven in.
• The rest is a simple reversal
• This took me 3 hours but it was the first time that I had taken a pistol to pieces.
Did it make any difference? Well the gun shot pellets and they hit the target and sometimes the holes were near each other sometimes they were somewhere random, to me it seemed to have enough power. With the new seals after about 10 shots they started to close up and after 50 shots I would say this gun is very accurate and seems very crisp.
Hope this helps
George

Diana/Milbro views and parts lists, Model-15, Model-16, Model-22, Model-23, Model-25 & Model-27.

 

These appear to date from the UK in the 1950s or 1960s which would place them in the post-War Millard Brothers era. With many thanks to David (Troubledshooter) for permission to use his scans.

Original Model-6 air pistol owner's manual in English (1962).

 

With thanks to Des for these pics.

Note that the trigger adjustment diagram on page 4 is actually of a woodstock model 6!

 

 

 

Interesting to note that the literature attached to Diana mod 6s sold in Germany had the same cover artwork, but with 'Diana' in place of 'Air pistol'. Of course, in the years after WW2 Milbro owned the Diana trademark in the UK, hence the use of the Original mark above.

But in 1962 M&G clearly hadn't got around to having proper Original-branded artwork printed (although this manual appears to have accompanied an Original pistol dated 1972).

Diana / Milbro manuals.

 

First posted by Oliver Gilkes:

Well, I came into possession of a series of 'information' manuals for various Milbro rifles recently and so I thought that I would post here links to some scans in case they are of interest or use. Feel free to download these from the VAG site if you wish, or use them as you like, public access should be set. They are in essence merely parts lists, with a few basic instructions, though the later rifles, the Bobcat and G80 have longer and more informative write-ups. I suppose this was Milbros attempt to modernise its image, a great shame it did not work ultimately, and I suspect that the restrictions placed on them by the old M&G plant which they seem to have been using to the end were simply too great.

So, a blast from the UK industrial past!

Model 100
And finally, an enigma. This is the Diana/Milbro model 100. It is an underlever, with seemingly a sliding breech mechanism. The only other underlever Milbro produced was the Model 55 - the Diana 50 look alike. This one is later, it has the safety catch that dates it to the early 1960s, however, it never seems to have been produced, unless someone knows differently. There is a ref to it in John Walter's Airgun Book, and there is this parts drawing I have been kindly provided with. Was it meant to be a replacement for the model 55?
