AND you are right ! Once you really get into it is (drum roll) a Walker trigger w/o the dual sear and lots of epoxy.
The usual three adjustments are there, just all gummed up with nasty epoxy.
I left the sear engagement and overtravel alone as they were okay.
I cleaned the epoxy out of the trigger pull allen screw hole, the lower one on the front, and backed it out.
Instantly 3 pounds ! I then played around with that screw and the new one on the trigger and ended up with 2 pounds, 8 ounces.
Crisp and tight as good as my 721s and 722s.
There is one thing odd about this action (from when it came out of the box) is that lifting and dropping the bolt handle does NOT cock it as do all my 721/2s. The bolt must be move to the rear just a bit to cock it. Is that right or do the engaging surfaces (sear and cocking piece) need to be stoned back a skosh ? (NO I'm not sending it back to Big Green).
Of course I went and ordered the Timney before fully understanding what I had.
Thanks for all the advice and suggestions.
