Thanks for the pic.
No what I picked up is something different again. might even be a base for a vice !
Mike - the scout carrier is the mirror reverse of the early original Mk1 British Bren Carrier, fitted with WS No 11, Boys Anti-tank Rifle, Bren Gun and crew of three. Seems to be the only one still in existence (so far) and it must have been one of the luckiest days of my life to stumble onto it in a Western Australian farm rubbish dump.
As for the K9 Austin, it seems to have been roughly the same model as Bob Dimer's Radio truck about 1952 I guess, but this one had the Steel GS/ Cargo body. mechanically complete and may even still run but the body is useful only for straining the tea leaves from the bottom of the billy !
Cheers
