SCORE! Enjoy!
It's a Weck hair shaper. I think they are mostly used for women's hair cuts, but without the guard it is a shavette. They also made the Sextoblade that was a little bigger and had a shaving guard.
You did GREAT. Is this a place you visit often? I'm really jealous but I'm glad it went to a good home. I'm also glad people know there is a market for this stuff!
