Closed 1541-II Newtronics/Mitsumi drive head or an ALPS drive to swap mechanism

I am after either a working drive head for 1541-II Newtronics/Mitsumi or an Alps drive mechanism (could also be a full 1541-II drive in an awful external condition as long as it has a swappable working parts inside). Just got Chinon drive for swap, but still interested in the Mitsumi head.

(that will teach me not to buy "seems to be working, but sold as untested" hardware heh).
