Great looking cars...this is tinplate, so..scale details don't matter.
It would not take much to add a few "european" details to the engine or cars....
I don't think we Americans would be too upset about proportions or exact detail...we just love tinplate for what it is.
Always liked green engines with red wheels and lots of nickel trim!....
How about it MIKE!
Maybe some more cream bodied, red or green roofed passenger cars with dark green or red trucks?
