Hello from the new guy! I have been working on restoring my grandfather's Harrington & Richardson unmarked 38 auto ejecting top break pistol. The gun was in horrible shape when he past away and my dad has held on to it as a keep sake for ever. I finally pried it from his hands with promises of restoration. I have researched as much as I can on my own but have hit 2 road blocks now that I've gathered what I believe to be all the needed pieces to put this back together. 1st: the lever doesn't seem to remain correctly engaged with the lifter. I can put it together and install it in the frame, it will function as desired about 2-3 pulls of the trigger but then jumps off the pin on the side of the lifter. I have examined it and even gotten a replacement lifter with a nice pin but the lever seems extremely loose fitting around this small pin off the lifter. Does anybody know how tight this union is supposed to be? 2nd: the replacement sear spring I purchased doesn't seem to want to stay in the up right position between the trigger guard and the sear. Is there a trick to getting this spring to stay in place properly?
