Hämmerli Sparkler Mod. R

Hi, I have bought a sparkler, condition was unknown as the auction site had one very bad photo of a pile of three rusty pistols. The price was right so I took a risk and bought. At the time I wasn’t sure what type it was, having picked it up it’s an R model, round bb only. 
so it’s a bit rusty in places, but not terrible and there is a bit of alloy bloom round the front sight but again not to bad and will probably just go with cleaning up and stabilise the finish.

have ordered some 8g co2 and copper washed lead bb’s so once they have arrived will try, I expect to hear a loud hiss, but maybe not, hopefully. I have put photos onto the photo host but don’t know how to attach them to the Sparkler article or add photos here?

if any one wants to do it or tell me how that would be great!

Thank you for the photos.

i have stripped it apart as far as I can see to go, no stuck or damaged screws rust in the sparklet chamber was just surface rust that cleaned out with an oily rag.

im going to need help with the next bit. First up is the end cap that holds the sparklet in, there is a washer on this that seems to be largely ok but has lost its give. Is this made of leather, rubber or something else? And more importantly can I get a spare or do I need to make one?

the second bit is the co2 control, this is inside and appears to move easily enough with pressure and didn’t feel stuck. The pellet probe undid easily and was only finger tight. I’m assuming that this is two parts that screw together? But hope that someone here knows and can tell me, even if the advice is leave it alone till you know it’s broken. I am assuming that there are rubber seals inside unless there is a very fine metal to metal fit.

i have also uploaded some more photos of the stripped pistol.

any help or advice gratefully received

"Congrats - you have the scarcest variant of the Sparkler dates from 1958. In the end cap is just one large seal. I have seen two types, a white / grey rubber material and a semi clear synthetic material like nylon. Generally these are ok and just cleaning will restore them.

"I cant see your dismantled pictures so don't know what type of valve you have in the Sparkler. If you have the 'top hat' brass seal in it, it will need a new seal in the 'top hat' as the original will have turned to mush. The 'brass 'top hat' comes apart by unscrewing the top section from the lower probe. Easiest way to do this is put the probe section in a drill chuck and spin it, then gently grip the top section using a glove or cloth and the top will unscrew. The 2x seals for the main body are 13mm x 3mm. Just make sure you use seals that can withstand CO2 gas."

@markd thanks, and Garvin has added the photos that I have so far, these show a couple of interesting points, first is that the machining in the barrel section is there for the loading tap of the D R variants, which then have the shroud and frame cut away to expose and the other is the lack of blueing or finish to the back of the barrel section, not just missing but never there.

seals needed will have to be urethane all other will absorb the gas and swell 

all parts will have to made or sourced and your R and D work may or not work the first time 

we had one rebuilder here in the states and he was work in to his 90's and had all the remaining parts that were left in the USA, he worked for Hammerli 

but the when Tropical Storm Harvey stuck Texas his garage was flooded and the remaining parts got wet and he throw them all out 

parts sizes--O-ring and seals-- are not written down anywhere so us Hammerli owner can, could fix them and even the knowledge of how to take them apart without damaging the patient is hard to find if at all

they are great old pistols but they will be deck paper weights as time passes 

just some observations from an old man that has a Master model Hammerli
