There is a range of toys Australian Made by Thomas Hore Toys. These are made of plastic and are large relative to the common 1:43 scale die-cast models of the era, probably closer to 1:24 or even 1:18.
I have limited information on these models but have confirmed that this large plastic tray truck that is in my collection is most likely made by Thomas Hore an associate or a peer of John Brent and Alex Tolmer.
My model is a flat bed or stake side truck which is missing the sides, at least there are holes where sides could have been fitted. I have seen pictures of a cement mixer and a dumper truck on the same cab chassis which are known to be Thomas Hore models.
If you have any information on Australian Made toys like the Thomas Hore range I would appreciate hearing from you via the Tonys Toys Contact page.
