I like the cabinet - I saw an ad somewhere on internet showing an ad for one like that and it said it was from 1951 for either the 15k or the 201K. When I did a quick image search for nahmaschine (spelling?) I saw several like the one above. Maybe somebody from Germany can translate (evidently can translate in browser but with dial-up I don't try) or give more information based on visible information. The badge isn't like what I thought even the German Singers had. Also no visible serial number where they are located on most Singer treadles I've seen.
