I have a Hw99 and want the barrel shortening and threading. That's the easy bit. The hard bit finding someone to do it for me. My local gun shops don't have gunsmiths, the only gunsmith who does do this can't get the breach block in his lathe. I don't want to give it to a general machine shop, I want someone how knows what they are doing.
So can anyone point me in the direction of a suitably equipped individual.

The air rifle I am putting together is a copy of a mates rifle that shots really nicely, unfortunately the guy that did his barrel is no longer with us
