7.8mmmm special tube manufactured by Burroughs

The B4024 is a clear glass miniature nixie tube manufactured by Burroughs. It can display numbers 0-3 and the letters "G" and "M". It seems to be very rare, because there is little to no information available. It is likely, that the specifications are the same as for the B4021 and B4022.
