15.5mm symbol tube manufactured by NEC
The LD-753 is a clear glass symbol tube manufactured by NEC. Currently there is not much information about this tube, but because of the shape it might be used with same-size numeric tubes inside a measurement device. The tube can display the Kilo-Ohm sign, mA, V and KC (kilo cycles - old unit for Hz).
