Here I was, innocent bystander. Not even somewhat aware of the enormous rabbit hole that you so casually pointed to and just in passing , "measurements? anyone?"
Ya, sure, did you want the on screen, on screen stunt, autographed, authenticated, replicated, recast, signature toy series, knock off toy series or the seven dissimilar but all specifically rare originals on salecor previously on sale in any number of TOTALLY AUTHENTIC RARE PROP AUCTIONS......
Three separate measurements claimed for supposed SD made models. All exclusively held by Keaton and the Easter Bunny, And with signatures from both.
Sorry brother, I am letting this one fall away, I am officially recapturing those lost brain cells for something far less likely to be a forgery, like, say a Ming Dynasty vase.
Good luck. That was the worst 20 minute search of my lifetime. I have reconfirmed my distrust in humanity.
