I just brought a 34 back from the dead myself. The yoke that holds the two screws at the front of the receiver was broken off and I had to mill it out and retap it. Blue mostly missing from the receiver. But after some rebuild & parts i've got to say it's pretty sweet..
Thank goodness I didn’t have to do that much work, but I’m satisfied with getting it going again. Great job on your work and definitely wish I had your expertise.
The 34 is in kind of a league of its own. It has a bigger piston and longer stroke than an HW95 but has a smaller piston and longer stroke than an HW80. The 34 is a pretty awesome little gun that can be tuned for a pretty wide range of velocity while still shooting well.
Have one of those too, should I bring it along with the R7 .20....lol. Owner of a gun shop fairly local takes trades and did, then it sat in his store for about 6 months before I wandered in asking. Made me an offer I couldn't refuse and I walked out 20 minutes later with the 34 and a soft sided gun case he tossed in to get me to take it and only cost me $75. Shoots very nicely already but there's an ARH spring kit and Vortek seal in the parts box if I ever get around to tinkering with it.
I got mine(.177) set at about 10fpe and its very easy to shoot. I had to do a bit of "barrel bending massage" to get it dead center of adjustments on the rear sight but it was pretty easy.
T01 guns don't have any T0 markings, since when they were in production, there were no other triggers around.
