That deeply inset total ID area of the receiver near the rear sight (where you would find Thompson Submachine Gun stamped level with the receiver surface on a real TSMG) is consistent with how the MGC and other non firing replica guns are built.
My surmise is somebody found a 1970s replica non-gun and wanted to make a splash on the internet.
Even on the original 1927 semi-auto versions, only the one line "Thompson Submachine Gun" was milled out and "Thompson Semi-Automatic Carbine" stamped in the one line recess. (The modern semi-auto Thompsons are different internal from the original and external have no provision for a selector between the safety and magazine catch.)
