On my K-Line GG1s there is a small F on the one end of the engine which is apparently denoting which end is the front when the engine starts up. At least that is the way it works.
But, on the Williams GG1, the F is on both ends, a different end depending on which side of the engine is facing you. Is that a "we copied it and made a mistake" mistake?
Does the Lionel GG1 have the same as the K-Line ones?
