[GreenKeys] Transformers

[Tom Kleinschmidt]

Hi all, related but off topic.

I am trying to help,a friend get the specifications of Western Electric
audio transformers. As WE is related to Teletype and many of us have broader
knowledge and interest I am hoping the collective brain trust has some info.
He mentioned the "IBS Master Handbook" and a card file system published by
WE as possible sources. Any direction would be appreciated!

Thank!
Tom
