Charlie, your work looks great on these 4-4-0s! The biggest thing that bothers me about these Lionel engines is that the drive wheels aren't spoked or even appear to look like they are spoked. Talk about a first world problem, ha!
Anyway, if I had one of these 4-4-0s, I'd be tempted to paint the spaces between the spokes a flat black to give the illusion of spoked drive wheels.
