January, 1931 Westinghouse Instruments, Relays and Electronic Devices, Catalog 211 This Manual appears to be read, used, stained, missing outer cover. I will ship via Media Mail due to the crazy cost of Priority Mail these days. If you want it Priority ask, and if you pay for the $10 cost I'll mail it Priority. Published by Westinghouse I guarantee all items I sell to be in, As Good As Described, or Better Condition. Thanks for looking!! BTW - I am out of the shop from Sunday - Tuesday. This means orders made on Saturday, (afternoon) - Tuesday, will be shipped on Wednesday. ALSO: I HAVE NOW ADOPTED THE POLICY, THAT I WILL NO LONGER LEAVE FEEDBACK FOR BUYERS UNTIL -- AFTER THEY LEAVE FEEDBACK FOR ME. THIS IS TO PREVENT LEAVING POSITIVE FEEDBACK FOR BUYERS THAT TURN OUT TO BE SCAMMERS AS MUCH AS 30 DAYS AFTER PURCHASING AN ITEM. I am very sorry that this has become a problem , unfortunately, and I thank you for your understanding. PLEASE!! LEAVE APPROPRIATE FEEDBACK AFTER YOU RECEIVE YOUR ITEM, AND I WILL PROMPTLY DO THE SAME!! THANKS!! DON.
