The rifle arrived today, its a 1991 model in quite good shape.
The hook on the trigger that limits its travel out of the trigger cage was the broken part. I fixed it with some wire from a broken BSA meteor sear spring, which was glued in place with cyanoacrylate after melting a track for the wire in the plastic part- success!


I glued the rear guide back together, assembled the miss-assembled trigger mechanism, cleared a 3mm ball bearing from the 30 year old piston seal, lubed the piston seal with some anschutz gleitfett, put some JM moly paste on the piston skirt and lubed the spring up with a little CV-joint grease.

The gun shoots, and although the shotcycle is fast and the gun does not vibrate very much, it still proves that the earlier short stroked and softer sprung D34 is a much better gun than the later D34!
