1954 Era Browning Superposed Buttplate/Pad

[Pay Dirt]

Browning has a factory pad that was worn by a lot of their guns.
Looks like yours still has a curved butt. Why not try to find a butt plate?

[Bill Murphy]

That gun is no magnum and was made with a horn buttplate on a curved surface. What is the length of your stock from the middle of the trigger to the middle of the wood at the butt? What is the exact width of the butt at it's widest point and the length of the butt without the pad installed? You might get lucky.
