Uh oh, looks like these were subbed out to the painters at the Lionel factory.
Just have Harry Heike weather it, you'll never notice.
RickO - Nah, I tend to think that given Lionel's recent quality control issues, MTH would not have subbed out these engines to the painters at the Lionel factory. Instead my guess is that the same firm that did MTH's 'FURX' engine did THESE engines too, and decided to use the leftover paint from the previous run. Either that or there was a paint sale over there.
