Westinghouse Type U Graphic Voltmeter

Unavailable
Westinghouse Type U Graphic Voltmeter, I don't know anything about this, but someone was good enough to e mail us and gave this information. It is a very old chart recorder and was used to chart voltage variations on the customers power line. Power companies still use the recorders today but they record on a paper disc. The unit probably dates from the 40's or 50's. Looks like it would need a key to open? Has paint wear but appears to be in excellent condition other than that. 10 x 7", metal tag reads circuit 60 cy & 280 volts on meter, Please don't ask questions on this item as I know nothing else about it. It came from a electricians collection. Postage will be 4.50 ups in the USA.
