Please do George, I'd love to see any pictures you have of your model. Your reply to this thread goes to show that there isn't much new in the world when you come to think about it.

This is another picture of the model that was used to apply for a patent for an anphibious army tank .It is about 30 inches long. It had two screws and a chain in the center . The neibour kids took a screw off of it and cut out some of the windows .A fellow by the name of Sam Cody invented it .He was a Canadian working in a munition plant in Detroit in 1917 .The American army was not interested in it because they wouldn't use a foreign patent in their army . The guns were to be put on after they got it working . The model had a wind up motor to drive the screws . George

Looks like something from Jules Verne George.

G'day George,
That is a very interesting model. Are you saying that the other screw has been lost? It looks like it's made from galvanised tin with the blade soldered to it, so perhaps a replica could be made. But then again - there's so many other things (like vehicle restoration) that could be done instead, and not enough hours in the day

Steve: You are right when you said no time . I put 350 machines in a museum .Mostly farm machines I am now restoring 13 military vehicles .and that's a slow process ,but most of them are close to the paint gun . This model is made of galvaize tin and solderd up The bottom is aluminum where the bearings go and the chain is like a byckle chain but the links are different .The windows are magnifying glass and I'm not sure how to fix them as they cut the holes bigger and to fix them with out painting it would be hard .Tow little boys that wanted some things that they didn't need George
