It had the original leather piston seal with it and the tp was at 4mm. I sleeved it down to 2.8mm and put a modern piston it it (still got the original) . What I was later told was a giveaway was that the trigger block had a steel guide threaded into it but I had already removed it and replaced it with a delrin one.
Another HW35 modification that Venom regularly did was to replace the steel roller on the cocking linkage with one made from Nylon66, Gary --- The Nylon roller stops the Weihrauch click when cocking.

All the best Mick
I wouldn't know Mick as it was changed for a new factory standard one as it had worn just before I bought it.
Thank you for your help.
