Up for sale here is this vintage Western Electric KS-5483-L-40 relay, circa 1943/44 and Made in USA. This was removed from a piece of WWII-era Western Electric tube gear and has some of that yellowish anti-fungal coating or whatever it is on it. The terminals have some solder and wire bits on them but should clean up easily. This has a bit of wear but is in great shape and is guaranteed to work great for you. Please see my pictures for details.
US shipping and handling is $10, and international is $28. If you have any questions, please ask.
I have more relays and other vintage electronics listed--feel free to take a look!
