It looks like a 65-66 medium duty truck chassis. They did the same thing then as they do now...
My dad drives one of those at work, actually exactly like that, and interestingly enough they made those trucks all the way until 1998 with a Gen7 Dashboard and interior. Its weird, '80-'86 interior in a '98 truck.
I believe it's a long nose (custom stretched) version of that N-series truck in the top picture. The bottom picture is the original Super Duty T850-series truck.
Thanks for the responses to the question. I think Blue Goose nailed it. I had posted the same question on a couple of more sites. I got an e-mail from a friend that had seen the post and said he knew of the truck and that it belonged to a woman in Texas. He also noted that it was an N series Ford and that it would have had to have been stretched because Ford never made a long hood N series truck. I knew that I have never seen anything like it before.
The truck in the first post is a FT 9000, F for full conventional cab, T is for the twin-screw rear axles, 9000 is for a full length front or stretched front end that is diesel powered. This truck most likely left the factory with a 270 or 335 horse Cummins engine. My father and I owned one of these back in the sixties. Tom
