Are you looking for a modern copy cat replacement for the vintage military Dwell/Tach meter or are you looking for a copy of the instruction manual for a unit you have?
If the latter list the manufacturer's name and model number of the unit you have. _________________ Wes K

MFG is UMC Electronics part number 7367.It looks to be 1960's vintage. I need the operation manual along with the operating voltage.I looked at part of a Simpson unit which looks exactly like mine which says operating voltage is between 6 and 33 volts.Contract DA-11-070-AMC-1592(W)I believe the DA prefix puts it between 1953-1962
I'd advise to pay some, but little attention to the manufacturer or contract number. If the FSN/NSN 4910-788-8549 is the same, then the item is the same form, fit, and function, --- and so usually is any manual with that NSN/FSN on the cover. The military sometimes had many makers of the same item. Same NSN/FSN, same item, different makers, sometimes different manuals for the same exact thing. Left hand not knowing what the right hand is doing kind of stuff (too common in government). Trying to find a UMC Electronics manual for the same FSN/NSN as the identical tach-dwell meters made by AUL or BRUNO is like looking for needles is a pile of needles (good luck).
Perhaps I misunderstand your point.
My BRUNO with same FSN 4910-788-8549 as your UMC is 1960's vintage, but has a 1980's calibration tag on it. Would a few photos help any? _________________ Ron D.

The operative word here is "usually" but it should have been used twice (add one "usually" after the word function.
The same FSN / NSN means it met the same basic Milspec. The units can still be very different in form as well as operation. So be carefull trying to operate one manufacturer's unit using a TM specific to another manufacturer. Same with repair data and parts. _________________ Wes K
