Silverbear...I just got a reply from NBHAA , run by Leon Dixon who says my Hiawatha is a St. Croix model made by Cleveland Welding Co. So far no date of manufacture, but he is still checking. (Have patience he said.) I guess I may be getting a little carried away with trying to date this project, but when I ride my current MaB around my area in Iowa, I get all kinds of questions about it. When I get the Hiawatha up and running, I'd like to be able to tell people what year it is, what model it is, who sold it, whether it was made by a German or a drunk Norweigan (lol) Its kind of like getting an old Ford mustang and wanting to know more about it than it's a Ford. The Hiawatha will be a MaB, and I'm just out to have fun with it. I've been looking at the fake tank, and I don't think it is suitable to make into a gas tank, because of the way it sits in the frame. It covers too much of the top and bottom tubes and is in two pieces. If I connected them, it would make it too tall to fit into the frame. I'm in the planning stage for making a similar tank that will fit. I'm also going to see if I can find decals for the tank that match the original ones. I've been checking out your Indian Hiawatha build, and I'm impressed with what you've been doing with it. It looks like alot of work, but will sure look nice when done. I can only hope that with my limited skills, that mine comes out half as nice.
