Fox Collectors

I found this ah fox de restock 12 any idea if I can use it on my A grade 12 hate to buy and can’t use it

It’s a crap shoot. In theory it should be close but more often than not the fitment is not great.

Where are pictures of your A-grade for comparison? Over time the way the top-tang joins the frame changed. Early on it was a wide radius as on the stock you show. The wide radius corner on a 1910 gun --
By 1921 the radius was smaller --
Virtually square by 1929 --

here are a few pictures of wrist ser 25520 A grade bought as project stock was broken and had a hiddius repair also need a forearm I have the metal
