Does not appear to be marked. The roseood stock has tool box wear. This piece has been polished. A nice working pair of tools of a similar style. MA97112 Starrett, Athol, Mass Number 279 Radius gauge.
Black body retains approx.
Perfect working condition. This is a great small sized bevel square. Traces of original laquer remain on the rosewood and brass. The only defect is a slight bend to the decorative brass thumbscrew that could be straightened. A rare and desireable tool.
