There is a corporate charter record for Western Magnetics in Minnesota dated 1964. Maybe this is the same company. There?s also a tape head from Michigan Magnetics. Maybe a merged company? wrote: desire to make them internally so they probably contractef with a company already set up to do that. Who were the big tape head manufacturers at that time? Does anyone know? https://www.pdp8online.com/tu56/pics/head_label.shtml?small . read, write, and erase heads or some other combo. The "Record" notation on the above head's label hints to me this might be a write head. https://www.pdp8online.com/tu56/tu56.shtml . Thanks. Hadn't seen the Minnesota information. Found some references but not actual company info. Did find a reference somewhere it Canada, but I couldn't tell if it was original or successor company. At any rate, no web presence nor telephone numbers found (yet.) I've dealt with the SurplusSales (of Nebraska) many times. His prices are usually pretty high (not obscene, but just not 'surplus' prices I'm used to.) However, he is a first-rate dealer and when he says something is so, you can count on it. Never had problem with anything I was willing to *PAY* for. I scanned the list you provided and found only a few 'digital' devices, unfortunately. I suspect from 7 and 9 track mag tape drives. I will scan his site and send him a ping so he'll be on the lookout. -Gary
