Logically speaking, you'd assume that the 0000-frame Repros should measure 12/16" between the firing pins. It has been mentioned in this forum a few times that it is thought the 4/0-frame Repros measure the same 13/16" spacing as the 000-frame orig. Parker Bros. frames, similar to why do the 1/2-frame Parkers at 1 1/16" measure the same as the 1-frames? No logical explanation, they just do. Sadly, I did not have a tape measure with me at the 2014 Antique Arms Show in Las Vegas to measure the pin spacing of the only 4/0 frame Repro I've ever held. Hopefully, someone that actually owns one of these uber fascinating 4/0-frame Repros will come forward with the definitive spacing -- until then, I guess we're just assuming.
