Thanks for the input J, and comment, Joe. I found a pic (somewhere on the net) of SP 7948 GP40-2, which does not have number boards at all on the long hood. I also noticed the light configuration on the hood was on a "beaver tail". I'd prefer the model to be prototypically correct, but it seems I would have to change the number completely, the scheme (speed lettering or not), or just accept the model as a fictional representation. The shell of this model is of a GP40, not a GP40-2. So let me ask the audience; would it be feasable to place numbers on the long hood boards, in either font, (or both!?)

or, what font would be more prototypically correct for this model locomotive?
