It looks like a dukes mixture of 35 & 36. 35 did not have a rear bumper. Late 35's had a change in the A pillar where it meets the cowl. Change from sharp angle of 35 to curved area at that part of the body like the 36. It sort of looks like a 36 grill on a 35, but really can't tell from photo. Pickups did not come with banjo steering wheel. He has a banjo on his, like I have on my 35. Pin stripe in wrong place for 35. It should be below the belt mold on the hood and doors. About 5/8" if my memory serves me right. 36 pinstripe in center of belt mold. Hood louvers should not be pinstriped. Horn (one, on driver side only, should be black, not chrome. Large belt mold across the dash should be black, regardless of body color. Tail lights too high up on stake pockets on bed. 35-36 pickups did not have inside mirror. Tail gate hinges should be body color, not chrome. Windshield frame should be painted body color, his is not. Grill bars are painted black. So are mine because I like the look. Grill was totally body color until I believe mid 36, and you could order it with the grill bars painted black.
Hey, I have picked enough nits. It is a beautiful truck, and I would love to own it. I am sure he restored it to please himself, and not to be point judged, just like me.
