That looks like an original 5 speed knob, along with 71A gearbox, TM-1081ZB(S) radio, steel fan and even exhaust system (possibly missing outer tip). It doesn't mention matching #'s engine though! The door ain't too bad, you can get a lower half of the door patch panel from Tabco. I am actually inclined to repair existing doors rather than go for the rare spares complete skin as the fitment is better on the OEM door skins.
It looks like it was blasted back (all filler removed) and some of the rougher areas exposed. The rear 1/4 panel probably being the worst bit, along with roof. It has some unusual rust spots too, probably from filler being used incorrectly!
It actually has a lot going for it, despite the current appearance.
*Edit HS30 01311 has been passed around quite a bit lately... first showed up as shown in photos here. (Wonder where the steelies went?)
