Lovely 1940 Ford School Bus on display at the Early Ford V8 Foundation Museum in Auburn, Indiana.
Notice that this Bus has the V8 symbol pressed into the Hood side which only the 1940 Ford Commercials had.
In 1941, Buyers had a choice of a Six cylinder engine in addition to the regular V8 engine. Therefore, the Hoods of the 1941 models were plain, so that Ford Motor Company didn't have to offer two distinct Hoods for 1941. Also, the Trim on the centre of the Hood extending down into the Grille is much wider on the revised 1941 models.
So there you have it. This is a very nice example of a 1940 Ford School Bus on display in the Museum.
