Your byf is certainly nice rifle and I appreciate you sharing the link
From I have learned thus far, the stock is correct for byf and seems rifle is an early-late war BYF 45.
The inside of the stock shows no signs of sanding and does not show any numbers that I can see
which I been told is correct also. Inside the stock is weak waf and a inverted " V " symbol.
Thanks for your input on this ....
