The Talking Machine Forum — For All Antique Phonographs & Recordings

I wanted to know if 1) is this a Analizing reproducer, 2) was Columbia the only company that used the spring mounted long throat reproducer, and 3) were any of them unmarked (without the patent information behind the mica)?

1) Yes
2) Don't know, but probably patented by Columbia
3) Unmarked reproducers are found on the client machines

This is a Columbia Analyzing reproducer. There are many different types. The earliest ones had a thumbscrew and the last patent date was 1886. These came out in 1902 until 1903. I'm sure Victor sued Columbia and they went to the spring loaded needlebar. The next one used the spring loaded clamp. These came out in 1903 until around 1904 or 05. Then the last of the branded Columbia machines used this reproducer from 1905 on. The unmarked reproducer was used on the Client machines like the Standard, Harvard, Oxford, Imperial, Englewood, just to name a few. The Analyzing rear mount reproducer has the last patent date of 1906. These were used on the BH, BI, BD, etc. Like the unmarked longthroat reproducers, the rear mount was also used on the client machines.

Exhibitions with a spring release lever are occasionally found. The spring release feature are much more common on Columbias. Jerry Blais
