B65-343 TURNTABLE PLANE. Foster Patent. Super 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. 10" sole with "100" and "7" cast behind the frog and "100" and "4" on the reverse side of the lever cap. 1-3/4" Ohio Thistle cutter. Beech tote and knob are scratched and large chip from end of tote; japanning retouched. One of the holy grails for collectors of weird and ultimately doomed patented planes. From the collection of David Jeffers, Good+ 2000-4000
