Are these WRA Firing Pins?????

Are these WRA firing pins? I was thinking the angle cut looks like SA
Thanks

I would have to say Winchester just because of the punch mark. But I'm usually wrong.

Wish it were that easy, SA parts can also have punch marks

Billy Pyle's "The Garand Stand Report" Spring 2004 No 54 has line drawings of Winchester, Springfield and reproduction round firing pins done by Charles Redfield with acknowledgements to Bill Ricca.

The top angle on the Winchester firing pins is 55 to 61 degrees while Springfield is 26 degrees. Your firing pins appear to me to be Springfield. Reproduction round firing pins have a difference in the shank slot
