I would think that some sort of either a press on dry transfer (like the lettering available in Art Supply stores) or a gold decal (a la Martin), both under lacquer, would be the easiest way. I know that the old model magazines, in particular Model Railroader, had custom decal suppliers for the model train fans. As for where you would get a dry transfer style logo made, perhaps a sign painter would be a good place to start. You know the ones that letter the glass on business front doors. In the old days the Doctors, Lawyers and Indian Chiefs had gold leaf lettering on their office doors. Perhaps someone can still afford real gold!
You'll probably need to supply the art work in the size you want to use on the headstock logo. Let us know how this turn out.
