According to Pat Hammod's book on Rovex, the Tri-ang Countryside Series, originated with a firm called Young and Fogg, who specialised in making rubber toys containing noise-makers. Tri-ang asked them to produce a range of rubber buildings. In the end, they were made by IMA Ltd, part of the Lines empire, who took over the firm.
My model is the R363 Forge. Manufaturered in 1960-62, price 2/11. Pat tells us that 1886 models were produced, all sold in plastic bags with a card header designed to hang on a hook in the shop.
Sadly, the rubber shrinks and dries out, leading to the mishapen appearance. These are rare, but those examples I have seen, are all affected this way.
I think I probably got a bargain here. Mainly, because so few people knew what they were looking at, and even fewer wanted to add the model to their Tri-ang collection as I do. It just shows, if you keep looking, there are jewels out there...
