Hi all,

Does anyone here know anything about these PHILCO tool-sets?

They pop up from time to time at flea markets, CL, eBay, etc, but nobody in the vintage tools community knows much about them. They are 1/4-inch hex drive. The sockets are 1/4", 5/16", 3/8", and 7/16". The tools are not marked. The only marking is the "PHILCO" on the lid and the reference to the US Patent and Trademark Office.

What was their purpose? General radio repair? Were they supplied with radios, akin to Singer Sewing Machine tool-sets, for home use? Or were these in Philco repair shops? Lastly, when? Do these date to the 1930's? 40's or perhaps early 50's? 

Basically, if anyone knows anything about these cool little mysterious PHILCO tool-sets, please chime in.

Thanks

Greg
