B66-703 MOUSE TRAP. Capito Original. This design was originally patented in Germany, and subsequently widely marketed under different names in the US. "Capito Original" is stamped in the top, which was one of the German makers. The idea is that the mouse enters the trap at the lower left and trips the sliding door that traps it, and then has no choice but to climb the tower, after which he falls in to the water filled container at the bottom, and in falling hits another lever that raises the trap door and resets the trap for the next victim. The fact that each mouse, when trapped, resets the trap, caused it to be advertised as the "wonder of the century." There's a Youtube video by a mousetrap collector named Shawn Woods that explains it in detail and demonstrates it. 10" high and 9" long, made of tin and cheap wood, looks like it works. From the collection of Jim and Christa Schoenky. Good+ 100-200
