18mm numeric tube manufactured by Reflector/Sovtek
The IN-12BV is 18mm end-view numerical nixie tube. Its dimensions are identical to the IN-12A and IN-12B, which are very common. This tube is rare, i have only seen them once, and you can't find any information about it. When i aquired this tube, the seller said it was military improved edition, but i have no proof that this information is genuine.
