These tubes are untested. Four of them have broken glass, but I bet if you have a nice vacuum chamber you could even make them glow. But really, this listing is for a B5991 and a 8422, which seem to be the same. Five are numeric and one looks like plus/minus.
The B-8422 is an american made end view nixie tube manufactured by Burroughs and National Electronics. There is a matching special character tube, the B-5992
