Gary: The lay out for the Tug decals came directly from the FJD Star Fleet Technical Manual, which as you know was the basis for the SFU license. That image lists it as a single word.
Rest assured though, now that you have brought it up - I will inquire directly and if necessary, changes to all future decals will be made.
Kent, hang on to your mini - it my become a 1 or 2 produced, collectors item!
