Up for sale here is this vintage Western Electric 251A retardation coil transformer, complete with 62A shield cover. This is in good shape but does have some rust, especially on the top, though it's not too bad. This is guaranteed to work. Please see my pictures for details.
US shipping and handling is $8, and international is $28. If you have any questions, please ask.
I have more transformers and other vintage electronics listed--feel free to take a look!
