Geiger counter collection

Collection of various Geiger counters and Radiation dose meters, early style military Geiger counter made in Australia in the 1950s and most likely intended for use at the then current nuclear testing ranges in South Australia during the 1950s and 60s. Another instrument is a Wallac survey meter, military model. 2 radiation counters using Dekatron display tubes and the newer Nixie display tubes. Issues with the Dekatron tubes, not counting reliably, a service manual for a Watson Victor counter is much needed!
