15.5mm numeric bi-quinary tube manufactured by Burroughs

The B5025 is an american numeric nixie tube manufactured by Burroughs and National Electronics. This is a biquinary tube, it has only 5 chathodes, and two anodes. Each cathode is sharing two digits. This feature makes it more complex do design a project using this tubes because of the requirement to switch the anode voltages. These tubes were manufactured in different shapes, and the ZM1030 / ZM1032 are very smiliar
