Very rare Rockwell Collins 312B-5 remote PTO for use with the KWM-2/2A. I obtained this unit from a Collins employee at the end of the only production run of Rockwell Collins 312B-5's. As I was told, only 25 units were produced to fill an order from a Middle East country. This unit was an incomplete unit missing the phone patch and directional coupler which I subsequently added from a parts unit. I have never seen one of these 312B-5's other than this one. I would say that there has never been an ebay listing either. The unit is in as new condition except as noted. See Rockwell part numbers marking on photo of back of front panel, plus the mounting of the Rockwell Collins emblem. If you have a Rockwell Collins KWM-2A, this is your chance to get the rare matching Rockwell Collins 312B-5 for it.
