This is an nice clean early 1900's era, leather strip cutting tool, with graduated inch markings on the adjustable slide gauge, up to 4". It's in good shape with a fairly sharp cutter. The graduated bar is a little loose fitting in the slot, thickness wise, but will tighten down with the thumbscrew. The screw tightens down on the width however. (We believe there was original a thin brass wear plate that fit in this are to make it easier to slide, the plate or shim is missing). The majority of the original black paint is on the handle, and it is rust free. Although this one is not marked by Osborne, it is basically the same tool as ones we have had that are marked. An interesting old tool!
