    Description

    Two TELCO (telephone company) repeat coils (transformers). Based upon some research, I believe that these are manufactured by the Automatic Electric company and are model 1200H. These were removed from working circuits during service changes. A brief check showed the frequency response to be approximately 50hz on the low end, and high end of up to 300 to 570khz, depending on which windings I use/check. These would be perfect for doing NDB or VLF antenna coupling.
    Both will be well packed and shipped via USPS priority mail.
