7204-033 Brass grooving plane. Cast brass body with iron cutter clamp and sliding fence. Fence is held by one thumbscrew that matches the cutter clamp and a common bolt, probably a replacement. 10" long, cuts an 1/8" groove. "York PA" and "Pullman" cast into side, a company we're not familiar with. The iron parts have some surface rust. A weird one. Good+ (GHR009) 60-120
