I am going to sell my JMR Model 40. I bought this a short while back. It was NOS. This mic is dated 1978. It is in fantastic condition. Cord is nice and tight. Mic is very clean. Mic is currently wired for 4 pin Cobra. Uses 7 volt battery. I will include an extra new battery. Comes with original manual and wiring guide for rigs up to 1978. This mic got great audio reports on every rig it's been on. Own the original and not the Chinese clones. $37.00 shipped within CONUS ONLY! PayPal gift payment only or USPS MO.
