Hoping you guys could give me some quick info on this trigger I have. The front is serrated(correct term?) vertically and about 4 grooves near the bottom. It is stamped on one side C 64032. With Vi shooters site currently down:crying:, and my Canfield book still in the mail, I need some help:sos:. I'll post some pics after I get the kids to bed:runaway:. Can someone please tell me when this type of trigger was used? Thanks, Mike
