At the Museum today, I came across some "Universal Release Magnet Kits, #87390" for use on M14 TDs.  It consists of a solenoid, a resistor, and some miscellaneous mechanical parts.  Paperwork is "Specification  S-5104", which I do not find on Nick's site (I'll send him a scan.)

Anyone know what this kit did or was for? 

Anyone want/need one?

Have fun,
