H1544
-mm special tube manufactured by Htiachi
The H1544 is a special character nixie tube. I found out that this logo on the tube is an old hitachi logo, so this tube was manufactured by Hitachi. It can display roman numbers from one to three, a minus sign and a special symbol. If you power the minus sing and the special symbol at the same time the letter E is displayed. There is a smiliar tube, the H1501, which lacks the roman three symbol.
