The wooden grips are different than my wooden grips. Interesting? The factory did not number the mags. That is why you will find different locations on the mags for the serial numbers. Mine is on the baseplate like Legacy's. I have seen others on the mag body. Warbird is the pro on this subject and he has seen far more examples than me. I know of an example of a phosphate "F", so the HSc is filled with great examples and history.
