Being from the 1930s, this Wappen nylon string guitar is more than vintage, it's antique! So antique that it was not strung at first with nylon but with gut (ox or cat) like all classical guitars did until the late 1940s - actually when all the gut was used as surgical thread for the wounded of the WWII, urging guitarists to discover nylon that was invented in 1935 and used so far to make fishing thread - a.o.
It's a German guitar, with a quite different design than the more regular models from southern Europe (France, Italy and Spain) that fixed the shape in the 19th century and made it universal. Germany's contribution to guitar design didn't start with electrification!
