B-305 PLOW PLANE. Twist Locking Arms. Just when you thought there was no other way to lock the fence on a plow plane, some enterprising soul came up with arms that twist to lock in the same way as a Star Tool marking gauge. Unhandled beech body with rosewood arms and ebony wedge and ebony boxing on fence. There's also a brass depth stop with a window in the fence to access it. Unmarked but the turned up end of the skate looks like Baltimore. Overall wear but no damage noting a big chip out of the wedge finial.Good+ 100-200 NOTE: Absentee bidding ends 5:00pm EST on Friday, March 29, 2019.
