[BC] Shure desktop microphone

[eliberat@fjc.gov]

A fellow employee got a hold of a Shure Microphone Model 450 desk top unit.
Do any of you know what the pin out would be for an XLR connection?  Can I
use a 3 pin male connector?

The wires are:
Ground
Black
White
Red
Green

Any information would be helpful.  You can email me off the list.
Thanks.
