Here's an early Main Line telegraph relay manufactured and sold by the Chicago Telegraph Supply Co. The relay is original throughout, and its condition is exceptional, very close to mint.

Clean hardware, clean coils. The enamel and decorations on the cast iron base are original and nearly flawless.

No missing parts, no replacement parts, no damaged parts.

Approximately 9" wide by 5" deep by 4 1/2" high.

A exceptional example of an early, seldom seen telegraph relay. Please review the photographs and consider them an integral part of the description.

I'm one of ebay's best known, most highly regarded sellers of antique radios, and I specialize in radios from the 1920's. I've been selling and shipping them for more than 25 years. When you purchase an antique radio from me, you'll receive a radio that arrives safely because it's been carefully packed (by me, not by some well-intentioned but nonetheless confounded, doe-eyed teenager working at the UPS store who wouldn't know a phonograph from a farm tool), Sure, you can probably get a lower price from Joe and Janet Barn-Find, but when your "bargain" arrives broken, and without any hint of how you might be able to put it back together, you'll realize that you really do get exactly what you pay for.
