Really great deal on that set! Probably was listed under US since the data pate says USA. My first set was a Canadian Mark III with appropriate power supply. Superior design but it had been gutted even though it displayed well.
The new set which replaces my old Mark II turned out to have matching serial numbers on the data plates for the variometer, power supply and main set which was a bit of a surprise. I'd only previously been aware of it having been made at the same location. On a related note, this one was configured for installation in a Sherman tank. Documentation and tagged wires indicates both 24v and 12v connections for power at the same time. I know the Mk III had a switch in the P/S Unit for 12v OR 24v but not both at once. Even a metal etched wiring diagram for inside the tank hull shows this with 24v being the positive connection and the 12v serving as the red wire which is the negative for the Microphone. Make sense to anyone?
