Need Info: Instrument from Rubicon Company in Philadelphia

Jan 03, 2005 5 Replies

I recently picked up this strange thing at a thrift shop. Trying to find out what it is. I know it isn't a radio, but figure some of you that have been around the block may know what it was.



It has Photocells written under the top left buttons, looks like contacts for a battery. GA under the other top contacts.



My guess it is from the 1930s-1950s



Pictures can be found at

Anything you can tell me on what the heck it is, I much appreciate it. You can reach me at snipped-for-privacy@gmail.com



Thanks much!


looks like an old "standard cell", but the "photocell" labeling is confusing.

Doesn't it have a nameplate? Pics are pretty fuzzy and it is hard to read the legends. Try placing the thing upside down on a scanner.

What does the upper label on the corner say?

This looks like it was made in the early 1930's to the mid 1940's. If I had more views of it, especialy clearly (not out of fucus) showing me the labels on everything, including rear views, I may be able to identify it. I am very familiar with many of the types of test gear and radio equipment from that era.

Resistance/ohm meter standard of some type would be my guess.

The 2 knobs fitted on it are UK military, circa 1939-1947. Maybe some lend-lease item?.
