WTB: Part for 1842 French Musket

[tsgalloway]

I'm looking for a reproduction or original wood screw for the 1842 French smoothbore musket. I'm specifically looking for the wood screw that is on the lock towards the butt end. Neither Lodgewood, The Rifle Shoppe, Dixie, nor SS Gunsmithing have this screw in stock. Multiple searches online also left me without a source. Any direction or guidance is much appreciated. Thanks.

Is the lock screw you are looking for a back-action style lock? If so, I have 1 maybe 2. It has a special head on it that requires a small spanner or double pointed screwdriver to remove it. P.m. me if you need this or if this is what you are looking for.
