It is indeed an N model. Our Rescue wing had P and N models. P's at Portland and N's at Patrick. This was a ferry trip to Kuwait with a stop at Bermuda. That is where the picture was taken. We were taking the plane over to replace a hangar queen that needed to be brought back to Patrick.
Pilotfly, Just curious - is that an "N" model in your avatar? I was on the "P" model in the early 70's flying over a lot of jungle refueling HH-3E's...
