I have several clones that don't have their original motors.
But at least the ones on there are black like the machines and don't stick out a pimple on prom night.
From what I've deduced many of the clones came in less motors and wiring. Then what ever distributor handled them put US type motors on them.
My HOTHER was made in Japan by JUKI, but it's original motor was a Belgelcor brand made in Belgium. My Sew Mor 404 had a Delco US made motor on it, but the cooling fan shattered so now it's got a Chinese made Alpha Sew motor.
I've also got a 1.5 amp motor made by Brother, I think, sitting on the sidelines waiting for a machine to go on. It's unpainted. So when it finds a home I'll tape off the placard and paint it to match.
