Wanted. Microphones to use with R2R Tape Recorder

[Cotlake]

Wanted. I have a Tandberg 9100X reel to reel tape deck. I would like to purchase or borrow for a short time, a pair of suitable microphones to use with it. They need to be terminated with 5 pin Din plugs or easily convertable. The microphone input specs are: Impedence 200-700 ohms, Sensitivity 230 uV, Max voltage (400 Hz) 35 mV.

Thanks in anticipation.
