Thanks Steve.

I'm guessing that if the company was bought out by Raytheon in the late

1950s the few transistors I have might be somewhat rare.

Additional history:

CBS's first television broadcasts were experimental, often only for one hour a day, and reaching a limited area in and around New York City. To catch up with rival RCA, CBS bought Hytron Labratories in 1939, and immediately moved into set production and color broadcasting. Though there were many competing patents and systems, RCA dictated the content of the FCC's technical standards, and grabbed the spotlight from CBS, DuMont and others by introducing television to the general public at the

1939 New York World's Fair. The FCC began licensing televsion stations on July 1, 1941; the first license went to RCA and NBC's WNBT; the second license, issued that same day, was to WCBS. CBS-Hytron offered a practical color system in 1941, but it was not compatible with the black-and-white standards set down by RCA. In time, and after considerable dithering, the FCC rejected CBS's technology in favor of that backed by RCA.

CBS-Hytron manufactured point-contact transistors initially . They dropped the "Hytron" for their first junction types.
