Wards Master #4 Smoother (My # 4-123117-1)
Wards Master was a house brand of Montgomery Wards. Most of them were made by Stanley. This is made by Stanley, probably from their Victor or Union line.
This is a quality plane, with Rosewood knob and tote, and a frog adjustment screw.
The sole on this plane was probably flattened before, however the frog still had mill marks, so if it was tuned previously, it was done with a milling machine.
Early Wards Masters were excellent quality. I believe they are one of the most cost effective Stanley made vintage planes available.
