I would say looking at the photos...it is not a 1977, because this is a 300 series.
I tried to zoom in on the hood emblem, in one aspect it looks like 361, then you look at the depth of the treadplate over the front bumper and you think 360. Again hard to tell from photos.
Either way...nice truck.
Does it run???. Looks like a Case tractor out in front of it in one photo.
All you need do is look at the plate by the glove box for serial number, or a clearer photo of the front plate over the radiator.That would give better idea on value.
Somehow the photos look destorted.
