13mm numeric tube manufactured by RFT

The B570M is a red coated nixie tube manufactured by RFT. It can display the number 0-9 and has long wires. Its very similar to the Z570M. Its unknown why the standard RFT/WF logo is not there, and why there is a "B" logo. Maybe this tube was branded for a different application
