My interest in WWI begins with the American involvement and my model collection is 1/72nd scale Americans and Allied armies that supported the Americans, as well as Germans who opposed them. So I don't collect early war, or theaters that don't involve Americans. I have been collecting WWI figures since my first Airfix Americans in the early 1960's. Recently, I have been trying to upgrade my collection and since I play one to one, I plan on buying, building or casting large numbers of vehicles. I am casting a couple hundred American trucks out of resin now.
I am slowly reading all the old posts and I am finding a lot of interesting and useful information.
