Gentlemen:
I am working with a early 1900's vintage SxS Box Lock and upon removal of the black composition butt stock plate I discovered a wood plug approximately 1/2" in diameter that is glued into a hole behind the plate. I don't believe this stock is attached to the receiver via a long through bolt, and if it were, it would most likely not be hidden behind a wood plug glued into its hole.

My thought initially was that a anti-recoil device had been installed during the gun lifetime, however, the plug/hole at > 1/2" diameter would most likely not accept such a tublar device. The double is a Featherweight. Anyone have an experience such as what I have described.

The parts list that I reviewed had no "through bolt" for stock attachment listed. Thanks for your input. B.M.
