Looks like a left-handed bi-metallic Merftervator to me. The dead giveaway is the high machine quality of the bevel on the face surface, plus the fine texture of the finish. See if a magnet will stick to it. If it does, it is an original. If it does not, then it is a Made in China reproduction. At this point it might be worth a pretty good penny if it is an aftermarket reproduction, especially after the import taxation now incurred from importing equipment from China. If you don't need it, you could try & sell it on FleaBay for profit or just hold on to it & let it go up in value & sell it later. Just my $.02 worth suggestions.
