I found these NOS shoes in my size, a swedish brand called Engelbrekt. Below they're pictured in some scans of a book from 1951, their 50th anniversary
More scans from the book on the blog where I've found them, some nice pics.
The shoes were made in Örebro, the center of swedish shoe production back then. Here's a film from 1940 of another shoemaker in Örebro, starting at about 4 min you get to see how they make a shoe (in swedish).
