Gentlemen,
It would really be nice to view more proof marks from the barrel flats area. After taking a closer look at the engraving I can see why you have your doubts, at this point I do too. As far as the metal to metal and wood to metal fit, particularly the wood to metal fit there are a number of factors that could be acting on that, such as an early ham-handed restoration job and perhaps there's rust blooms on the back side of the locks adding unwanted thickness where the metal meets the wood. For that matter the wood may have shrunken badly. Still, the engravings not Manton-worthy for sure. I admit I have a weakness for back action lock hammer guns and still feel it could be turned into a nice field gun, that is if the barrels are not too deeply pitted inside or too thin.
