I had a feeling the model # on the block would be different, what is the serial # on the block? My guess is it will show up as a 1941 production #. The typical TD-15 would be the same as the later TD-20s with the recoil (as illustrated in the photos Gary posted) only the motors were entirely painted silver. Decal would be red with white letters.
Just curious, are you thinking of restoring the motor back to original for the TD-15 (and finding a recoil), or will you keep it with the creative paint and the TS rope plate and surround? BTW, that serial # on the rope plate is only a few thousand shy of the 1946 allocation. Since the war ended officially on 9/2/45 and consumer restrictions ended fairly quickly, that rope plate likely belonged to one of the first post-war motors sold. My guess is that was the attraction to whoever previously attempted to restored it.
