Does anyone have photos or a good description of the military markings (placement and font) on the Benelli M1014? Thanks, alpha33 out...............................

Receiver or barrel markings for instance, something like these....

So no one has any idea how the US Ordnance Dept. marked their Benelli scatterguns? I'm fairly certain they did because starting in the late 18th century (1777 thru 1968) at the Springfield Armory, all small arms were marked.
