4X2 vehicle with steel tray - ID required

[Bruce Gilbert]

Hello from Sydney (Oz, that is!)

I need some assistance in identifying the following vehicle:-
1) 2 wheel drive
2) all steel tray with steel tailgate
3) Plate on side of tray says in part:-
3.1) "Canadian Top & ???? Corp Ltd
3.2) ?????? Canada
3.3) SN 4203 2 5775

4) V8 engine - both heads have screw-in plates, one which has what looks like "C81T 8060".
5)Red-painted wheel nuts
6) rifle butt holders on floor behind/to side of both seats
7) rectangular/square (not round) roof hatch.
8) No sign of nomenclature plates. (Q: Where would they be? Also, where would the chassis etc ID's be?).

All help and advise much appreciated. Can provide piccies in a few days.

Thanks
