15.5mm numeric tube manufactured by National Electronics

The NL-921 is a clear glass end view nixie tube manufactured by National Electronics. It can display numerals 0 to 9 and the left decimal point. The Numerals are alligned to the right inside the glass housing. I don't have any information on this tube, but it looks very similar to the NL-809
