Thanks for the info... The wood is definitely replacement, as it is not checkered. But it appears as it was originally a straight stocked gun, as the trigger tang is the long version, and the shape of the long tang is identical to the straight stock Flues Gr. 3 12 I have, except for the lack of engraving. And the metal condition of the tang is consistent with the rest of the gun. The gun was made in 1913, and has "smokeless powder steel" barrels.
The Stock has a black butt plate with a capital M in the middle of it. The wood used for the restock is consistent with a Grade 1 or 1 1/2, so I think I will send the gun out to be checked in the correct style, and add a period correct pad to the gun to get it to my LOP requirement.
