I would agree. I have one that looks very similar that is marked W M Moore Co. Belgium. My hammers, side plate and screw/pin locations are exactly like yours. My fences are not scalloped like yours and my engraving is not as ornate as yours. Mine is a 10 gauge with 26" barrels that measure modified and modified, it also has has 4 inch chambers and looks to be built much heavier than yours.
