I never heard that but could be. I did a fair amount of work for Bob at AM in Charlotte and at the reborn AM II in Concord. My brother in law was art director and design consultant for AM. If you have a AM B-25 kit....my kids packed it!!
I don't have any drawings from the GS Vette but do have some from the AM NASCAR Taurus that was made but never sold....that design was all Bob.
