For reference, all my parts look exactly like what Jeff Bonadurer initially posted to start this entire thread. Unfortunately, they differ from the shotgun and parts which Al had to create his pictorial tutorial...
In this photo (which looks like my shotgun), can anyone identify the part(s) circled in red and explain their function?
Or does anyone happen to have better photos of that part (those parts)?
Also, can someone tell me on what the ends of the sear springs are pressing (the portions circled in red) - those are the mainsprings, right?
Finally, Al, yes, I studied what you posted about installing the mainsprings, and that shouldn't be any problem once I actually get to that step... I have to deal, however, with a few other issues (and missing parts) before I get to that point...
I will upload additional photos of my own Ithaca Crass and post them for reference
