B68-543 TURNTABLE PLANE. Foster Patent. Extremely rare example of Edwin Foster's 1909 patent for a bench plane with a frog that can be rotated up to 45 degrees to either side. The whole story is at PTAMPIA I, page 218. Most of the handful of known examples have 9-3/4" soles with No. 101 and the patent date cast behind the frog and Ohio Tool Co. cutters; this one has a 15" sole and 2-1/4" Stanley 1892 patent date cutter. It has No. 102 cast in the bed and also in the reverse side of the lever cap, but no patent date. Beech tote and knob stained to resemble rosewood, small chip from end of tote, otherwise very clean, japanning 60%. One of the holy grails for collectors of weird and ultimately doomed patented planes. From the collection of Harold Unruh. Good+ 2000-4000
