In WWI the United States had many civilian companies devise tanks for use by the soldiers.
The Holt Company was one of them and the Caterpillar Company and many others.
Some like this one were just mock ups and others were actually put into production.
This one was used all over California for recruiting, training and propaganda.
Some of them were gasoline powered or even steam powered. Over 20 different designs were put forward. I think some model company should make models of all these in Minitank size so we can play alternate history or science fiction games with them.
