MR BILL: LOL, Sorry to say that it is one of Manny's cars. If you look on the Frisco website at his photo albums -- he must have a hundred cars, real beauties, that someone made for him. You really should try and look at them. There are sooo many different ones that had to have been made special decals. If I were you, I would seriously use every means available to locate him - as his knowledge of all those RR's would really help you.
Good luck with your quest!
If you do not mind: I will at least email him with your info and see if he will contact you? (If he is still around)
