I have just put my latest model onto ebay. It is a Great Western 45xx class tank engine with goods train in a livery appropriate for around 1935.
I'm attaching a photo of the test build. The loco is 57mm long.
I have given thought to producing my models at another scale but that would give a very different feel to the models. So far I have been trying to capture the feel of the old Micromodels, but hopefully with more detail. However, to take the models up to a larger size I wouldn't be happy without adding more detail to them. To get an exhibition finish would, I feel, need a gloss finish in a larger scale to give the feeling of polished painted metal. I'm not yet convinced that photo paper is OK to work with.
