Replacement Microphone for Omni Console

Does anyone know the part number, or the specifications, for the small button microphone inside of the OmniPro II console? I need a replacement and I'd rather not buy a new console if I can find a mic that will work.

Most any 3/8" diameter x 1/4" depth [9.7mm x 6.75mm] condenser mic of 1.2K ohms should work.   Often you can find a condenser mic with a solder pad at 0.382" Dia (9.70mm) but if you are not talented with a soldering iron, look for a mic with leads. Price is generally around $3 - $6

Thank you StarTrekDoors!
 
I did find many electret condenser microphones of that size on a web search last month - many with attached leads. My problem was with the resistance as there were a few different choices. 
 
I will order a couple 1.2K versions.
 
Thank you!
