Interesting home made set. The engine used was a later run 1948 350, the tender sides are not indented as on the very early runs. It was not a 1950 353 Circus engine because that engine did not have wire handrails. The cars are just standard Gilbert link coupler cars repainted with new decals. It shows what can be done with a little creativity.
Here are some pictures of the originals, including the 1948 Royal Blue set with cars.
