The Geiger Counter
The Geiger Counter Clock
These clocks are made out of original MOD issue Radac No2 Geiger Counters. All the insides have been carefully removed and in place a 6 digit Nixie clock, and also a Dekatron tube in the place where the old dial used to be located.
I had 5 of these original Radac No2 Counters, I only have Number 4 of 5 now left.
