My apologies for neglecting to read the rule about posting pictures. Mine
are too large in any case, so here is the information about the device for
which I want the schematic and/or service/user manuals.

On the side:  “OREMASTER Super Geiger Counters, Mfd. By White’s Electronics,
1218 M. Street, Sweet Home, Oregon”

The meter face has the same manufacturer information and has three scales, 0
– 20, 0 – 2 and 0 to 0.2 MILLIROENTGENS PER HOUR with appropriate switching.

It supposedly takes 22 ½ volt batteries and the GM Tube seems to be missing.

Anyone have any information about this antique? 

Thanks, Jim Darrough
