Rare Vintage 1950s Goldak The Colorado Geiger Counter Looks Hardly Used For Sale

This rare radiation Geiger Counter came from an old estate. It looks to be in almost new condition. It has not been tested as I do not have any "B" type Batteries. Its an awesome piece for a collector or bio technology student or even someone that wants it for peace of mind. The handle is only being held on by one screw. The other screw is their but needs to be screwed back in. Please look at all pictures for further condition details. The counter is being sold as is. Thank you for looking!!
