The pic you posted is one I originally took shooting various parts of Ken Barnhart's ZL1. it is 100% correct for anything post 1969.
There is a guy who is making a reproduction sticker for earlier style I'll call it the 1967 style. If I had one, I would want it to say Hurst. Heck you could probably put the repro sticker (it is on ebay occasionally) on the one you have.
