    Hi,

    I have four of these - they were inside a Martin Audio Signal Scrambler from prior to 1961. I also have the connectors. They are in a completely enclosed unit and measure approximately 6 3/8" L, 2 3/8" W, and 1 7/8" D. I'd really appreciate any info.

    Thanks

    Something manufactured by the F.W. Sickles Company of Chicopee, Massachusetts, which was a division of General Instrument Corporation.
