Mono Play & Record Heads For 35mm Film Recorder

This listing is for an interesting pair of 35mm film magnetic heads, in this case mono play and record heads. I've measured the inductance at 1kHz on an HP LCR test set and get 420 mH for the play head and 7.1 mH for the record head, which indicate plenty of useful life left based on my experience with other vintage tape recorder heads. These came in a large lot of mostly Ampex and Nortronics heads and I've finally got round to doing some homework on them. The package they were in had Magnatech noted on it and a friend who worked in the film industry in those days noted they also could have been used on a Westrex recorder. However I cannot positively identify them and would appreciate input from any of you who can help. I'll update the listing with any information that is provided. I'll consider any reasonable offers, especially if backed up with data - I cannot find any records of sales of these or similar in the last 12 months. Check out my feedback for all sorts of quality items and bid with confidence. Shipping quoted is for US lower 48 only.
