1939 S/42 Question

[Lefty14615]

Hi all!
I inherited a 1939 S/42. Every part including grips are matched to the serial number with the exception of the center axle or toggle pin and the forward breech block pin on the toggle assembly. They are both unmarked. The rear axle pin is marked on the end and matches the pistol Can anyone tell me if this is correct? Thanks Lefty.
