Found out a bit more info on its relatively recent history.
It was sold to the sellers father, out of Tasmania, maybe eight years ago give or take. Prior to that it was a bitza, with a ute cab on and trashy doors. The owner, a friend, replaced the doors and brought it back to what you see now, hence the different door colour/shade. in fact, it was another friend (now deceased) that sprayed them. He (my late friend) also had made an electric capstan winch with a starter motor, hence the two discolouration marks on the front bumper. I'd like to know where the capstan went, as I try to retain as much of his work as possible ... sentimental sod I am!
