I have an early Fox B-grade with all matching numbers. My question is with the stock. It is a straight grip, however the tang does not extend rearward as far as other straight grip Fox guns I have seen. It also lacks checkering on the cheeks which I have noticed on a number of other B-grade Fox guns. This leads me to suspect that this gun stock is not factory original and has been restocked.

What say you? Please see factory letter and a couple of pics below.
