History of Neumann M249b at CBS

by John

I was wondering if you might be able to help me uncover some of the history of a microphone in my collection.

It is a Neumann m249b with a serial number from the mid-sixties apparently owned by CBS New York.

On the back of the back of the microphone towards the base 'CBS' in small letters is scratched into the metal.

On the bottom of the microphone housing, the following is inscribed into the metal:

CBS 13-059-0730 NYCRN

The same letters/number series is inscribed into the top of the power supply. In addition, there is a large black "#3" written on the top of the power supply using some kind of permanent ink/marker. On the bottom of the power supply is a white sticker from Gotham Audio Corporation 1790 Broadway, NY NY. There also a piece of masking tape on the bottom of the power supply with writing in black marker something like "B 6dcc". I can't quite make out the last letters.

Would there be any written or photographic records of the use of this microphone in an archive somewhere? Would there be anybody around that you know of that might know the history of this microphone at CBS?

Any helpful information greatly appreciated.

Sincerely Yours

John
