I doubt if the RMA/RETMA/EIA would have allowed two different tubes to exist with the same type number. The RMA registration (to Sylvania) 10/16/49 shows NOTHING connected to pin 10. I suspect an error in the tube checker data. Do you get a reading if you tie the extra wire to the anode button?
I have never seen a 10MP4 ... what set was it used in?
