Hi Pete, of course I had to find out what the writing on the rear of the deck said, but it wasn't helpful:

Just the usual warning to keep your fingers out.

The brand, Tru-Bilt, is cast into the base, and it looks too big to be likely to be an insert for a "home brand". The brand is also cast into the wheels. Hence this is not a rebranded product made under some other name. The design of the base, with the tiny but elaborate rear grass door, suggests it is from a long time ago. I don't think it will be an Australian brand, because I've heard at least vaguely about nearly all of the ones that could have afforded to tool up a cast aluminium base of their own. The British would have been unlikely to use a US engine, or to adopt such colonial spelling, so it seems to me it will be an ancient US brand. However like you, I didn't find any trace of it on the internet.
