[Milsurplus] Another Whatzit

[Mike Feher]

Sounds like you got most of it figured out Bob. It appears to be an azimuth display from something. I guess the question is what, HI? The answer to that I do not know. 73 - Mike

Subject: [Milsurplus] Another Whatzit

I have an for the "Whatzit" contest, see pics at links below. This complete one and another stripped to the geartrain one were in some junk a neighbor gave me.  There are two syncros are Autosyn brand, made by Eclipse-Pioneer Div. of Bendix, Teterboro NJ.   There are stickers on each with a s/n and p/n saying "Mfd for AC Spark Plug Div., Milwaukee WI".      The motor is made by Oster Mfg. Co. of Racine WI, labeled "Phase 1 52V, Phase 2 52V 400 cycles", and "Low Inertia".     The fast-turning dial is marked 0-9 and the slow-turning one is marked 0-36 (presumable corresponding to 360 degrees).   The ratio is such that one turn of the fast dial = about .8 increment of the 0-36 one.    The only motive force is applied by the motor, you can turn the wheels by hand but it looks to me like they are only intended to provide a readout to the operator thru a window in a panel, although you can rotate the fast dial like a thumbwheel.

Very nicely made cast and machined frame and precision gears, looks like it could have been used in a piece of avionics or fire control gear - anyone recognize it?
