An early screw sided example with wedge and brass bridge. Unmarked, but clearly a Spiers. Screw sided examples are indicative of Spiers’ earliest work. Fine mouth, no issues or repairs. Stewart Spiers born 1820, died 1899, made dovetailed infill planes in Ayr Scotland ca. 1840-1937. Probably the best of all time, his planes exhibit elegant flowing lines that to this day are unequaled. A cabinetmaker by trade his first planes were made from rough castings purchased in Edinburgh. By 1870 plane making was his sole occupation.
