pre-Type-I Citori, and maybe Type-I....yea, I know parts are unobtanium, but was looking at parts diagrams and the pre-Type-I firing pins look identical to BT-99 firing pins. Correct, or near miss? They are both short stubby ones that are retained by the bushing from the receiver end, not pinned inside. Are the BT-99 bushings and springs compatible?
I have no clue, but I’m sure that Art’s does. Give them a call. Or MGW, they’re an excellent source also. https://artsgunshop.com/ https://www.midwestgunworks.com/browning-citori/parts.html
