I enlarged the picture, as much, as I could, on the first one, & it's definitely a '51-'53. Kinda looks as if it has push button door handles, which would make it a '52, or '53. If it's a '52, or '53 it would be equipped with a 302 engine. If '51, a 270. Also it has Factory tow hooks on the bumper. It could be a 450, or even a 470 series. Check the back of the glove box lid, for the tag that tells the trucks spec'd eng., trans, rear axle, etc.
