EXTRA FINE TYPE 1 STANLEY NO. 25 SLIDING T BEVEL SQUARE - 10" - 1858-1876

Superb condition as just discovered in a time capsule tool chest. Untouched, uncleaned. Crisp edges and gorgeous rosewood grain patterns. Not likely many better type 1's out there. Minor oxidization and a touch of scale on the blade. Initials MJ in small stamp on both sides. Shout out to Eric Benson's outstanding research at chapticowood.com which can be found below.
