A '72 Cheyenne Super SWB is a very rare and very popular truck.
It is also easy to 'replicate' with a few badges.....even easier when building it from several other trucks.
Did you check the frame to see if this was an original short bed?
Remember a few new badges and you will suddenly have what appears to be a 'Cheyenne Super'.
As well, its easy to add options to these trucks included a tilt wheel, woodgrain dash, etc.....so this means these items may not be original...and that might not matter to you.

There is a good chance it has been built from a different cab, doors, etc....this isn't uncommon.

Regardless, post up some pics of it including the 'SPID' (sheet) in the glovebox and we can get you some more information.
