[ RadSafe ] Old Geiger Counter schematic needed

[Darrough, James]

Hello.

               I am looking for a schematic and maybe user/service manual for a very old Geiger counter. It is called an "Oremaster Super Geiger Counter" and actually has electron tubes. I am attaching a couple of photos for better identification.

               If anyone has any literature on this old device, it would be much appreciated!

Sincerely, Jim Darrough
