The Webley Junior

The Webley Junior pistol has been around for a long time . I'm not going to argue over series or Mks, but just keep it simple. The all steel Juniors and the alloy bodied Junior Mk2's. Danny's site gives plenty of info https://forum.vintageairgunsgallery.com/webley-pistols/webley-junior/

The early models had an extended barrel and wooden grips, and then moved to tin grips. I have been told that there is no "Standard" length of the longer barrels, probably due to parts sourcing. Also some of the longer barrels may have been changed by Webley at some point. After the tin gripped models were changed to the black gripped models, which (as far as I know) all had the shorter barrel, the gun more or less remained unchanged until the Junior Mk 2 was introduced.
It is worth noting that the colouring of the frame that we like now, was seen as a fault and models were returned to Webley for re bluing. As Webley changed the mixture they were using, reblued frames will no longer fade to plum or bronze.
Some variations had "ears" on the grips and some models had a rearsight plate rather than the fixed sight.

A solid little pistol and very simple. I think there are about 29 parts in a Junior? Faults can develop, but they are mainly due to long term neglect. You can get the sear wearing or the holding face of the piston wearing, but these, (along with other Webley pistols) tend to be caused by force being used to try to cock a gun that the cocking shoe has worn on. Another problem, mainly caused by abuse is the lugs on the barrel catch breaking, usually when someone has used a screwdriver or similar to lever the catch out.

Like with the other early Webley pistols , you don't have to remove the trigger and sear to get the piston out.
The piston washer screw can be hard to remove and can shear off, so if you are doing it, be careful.
The breech seals may need sizing to fit, especially if you change to a neoprene one from a later gun. You will probably have to sand a fair bit off the back of the breech seal.
The mainsprings seem to be of such a length that you cannot get a slip washer in, or the gun wont cock. Also I've had a couple that needed a tiny bit off the standard spring. 
I have come across some guns fitted with another spring (maybe out of a gat??) that will be tight in the piston. These tend to shoot poorly and also "kick" a bit as the spring doesn't seem to rotate in the piston.

However, with the correct spring in they can shoot well. Ive found some of the fixed sight models can be hard to line up as the V can be stepped and also rounded.  I have been told that people used to file the V out to suit their eyes.

Something that you may find odd with a Junior is your hand is too big to get all your fingers on the grip, but you will get used to it.

Now all this doesn't sound very good, but remember I'm talking about guns that could have had between 50 and near 100 years of neglect. Sort one out and it will plink for many a year to come. For short range plinking, they are a fun gun and can be surprisingly accurate.

It passes the test----You can club someone to death with one and it will still plink afterwards.
