Do you have a broken part to your pistol or rifle?
I might be able to make a new one up for you provided its not too complex.
As I repair most pre 1980 Co2 air guns its not uncommon to find bits missing or broken, if I cannot find a replacement for the rarer models I have to fabricate the item.
if you cannot find a replacement part email me (zen65400@zen.co.uk) perhaps I can help? No promises!
I can reseal most pre 1980 Co2 air guns, and or get them working provided they are in one bit and not suffering from metal fatigue
