Today I purchased a Drulov DU 10 at an auction, upon inspection all seemed good it cocked and dry fired, but upon getting it home and popping in a new 12g co2 bulb I could hear air rushing out of it. TO THE INTERNET....
I found an excellent video on youtube showing the deconstruction of the pistol, so I cleared my bench and opened her up. This is where I hoped to find a damaged ball seal! (a 3mm or so plastic bush) But alas there wasn't one there.
I found a company in Poland selling them but wondered if anyone new of a UK stockist?

Many thanks

James
