Not unlike studio models, I'm sure WB could care less about Robby. There are far more famous props that have been done to death, by guys who didn't pay a thing to produce them. Did the studios do anything? Nope, there isn't any money in it for them. They want what's right now, who cares about something made 50+ years ago. Besides the original Robby(regardless of it's value) was considered disposable by the studio. Which was one reason they let it be on display in the Movieworld museum in the first place.
Barton is crazy thinking his prop is worth more than it is.
And he is even crazier not to offer parts, which means someone else will offer the parts regardless of any nonsense threats he can make. Which will mean he looses the money he could have captured.
I will be the first(on this thread) to call him a flippen hypocrite.
He sells the following parts to the B-9 robot.
Bubble and bottom plate
Arm, wrist and claw
Legs(vintage & reproduction)
Knees(vintage & reproduction)
Wheels and belts
Or look here
The B9 Robot Builders Club
And he sells stuff for other robots as well.
He knows damn well he would make money offering Robby parts. I guess the real question is, what's the right approach to get Robby parts from him.
That's the way the rest of the guys in the hobby work. Find out what he wants and seek a trade.
