Philco Frequency Meter BC-221-AE (1940's)
This has to be the oldest bit of kit i have, this used to belong to my dad, and has been up in the loft for many years (after his passing), i think it's from the 1940's, used in the 2nd world war, for the U.S Army, it would of been powered by a 135 volt battery (but at some point had been converted to run off AC), from the info i have found, this was used for calibrating radio equipment, by using a method called Zero-Beating, the Frequency Meter still works, but the dial reading's are a bit off from the setting in the Calibration Book, i did replace some of the components in the power supply to make it a bit safer to use, but for it's age it still works really well.



Here's a YouTube video of a newer Frequency Meter, plus the same model as mine (not my video)
