I’m building a propeller balance meter. This unit was designed and built for in-house use at Rockwell International (North American Aircraft Corp.) Columbus, OH.
There were approximately 200 additional units that were built for Rockwell's Aero Commander dealers around the late 1960s. It uses a velocity type pick-up which is what I need. Best as I can find out, it was a type MU 6-7 Pn. B 11032-1.
If anyone knows where I can get one of these pick-ups or what could be substituted, I would appreciate any help; a used or surplus part is preferred.
