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.
