I hunted, but couldn't find a Stanley with the rear ribs and not the front ones (other then an English version) I know the "cordovan" style had ribs, but it doesn't look like someone "refurbished" that one...Perhaps. But Montgomery Ward and Sears contracted for their tools. All the Wards Master's I've seen (and I own a few...) were made by Stanley. Sears contracted with Miller's Falls, Sargent and Stanley.
I've seen English Stanley's like the one you posted. Record also made some with a rib but different than the OP. I've never seen another maker with a rib.
I've never seen one like the OP...... it looks like an earlier version of the 1950's Stanley design. It could be a house branded plane but looks like Stanley to me.
