B63-647. ADJUSTABLE SMOOTHING PLANE. Completely unmarked and we have no idea who made it, but it sure deserves to be patented. 8-3/4" long with dovetailed lignum sole and European style front horn. The cutter depth is adjusted by a toothed wheel st in the right cheek. There's a lever to lock the wheel in place when the depth is set, and a hole that may have held a pin to lock the lever. 1-3/4" cutter with plated lever cap. The throat is adjustable with a locking screw behind the horn. Ingenious and intriguing. From the collection of Cliff Sapienza. Good+ 150-300
