I think he's hoping.
Scrapped one of these about 4 / 5 years ago.
Even offered it for free if anyone wanted it but no one did so it got scrapped.
They were a good idea for what they were intended, shipboard / submarines etc but they take an inordinate amount of room up for very little capability.
At first glance they seem the answer to every Model Engineers prayer but at the size and weight they are a non starter once the green paint fever has worn off.
After that you move onto serious hobby user / light industrial and the short comings become even greater.
This is one of those machines that would be best in a museum as a look at what was but not as a day to day working machine.
