From the ebay description of Ron's Sub:
This was a one-off, exhibited in Falmouth at the "All Hands On Deck" exhibition in 1998, at that time entitled "Pink Submarine". I subsequently bought it direct from Neil, and have had it ever since.
It has recently been restored to full working order by Neil in his workshop, but unfortunately I can no longer keep it. There is no reserve and the starting price is less than I paid for it more than ten years ago.
It is 24" high, 25" wide and 8.5" deep at its fullest extent - a large piece!
See the video for how it works - the piece unfolds the sad story of Noah's brother Ron, who unwisely opted to build a submarine rather than an ark, and due to the regrettable actions of the legendary fauna on board, came to a watery end along with his cargo of dinosaurs and other fantastic, and now unfortunately extinct, creatures.
I wish I could be the next lucky owner of this one!
