19mm numeric tube manufactured by Rodan

The CD11 is a round nixie tube manufactured by rodan. It has a very unusal shape and massive center pin. The anode grid on this tube is very transparent, allowing avery nice image of the digits. Personally, i really like this tube. Its very uncommon and usually hard to find
