http://www.freewebs.com/indianarog/ This site is run by Roger who has a very nice web site sort of based on one of his heroes I think. He shows off his many engines, explains some history and stories about them, and has a very helpful section on restoration and maintenance tips.
http://www.jensensteamengines.com/ This is the web site [set up by Steve] of Jensen manufacturing--which is the only U.S. company that I'm aware of still making miniature steam engines. Not only do they show you the engines that are still being made, but they also have a section about how to run your engine, parts for repair, and a museum of some of their old engines. They also have a great section on their small staff and how they build the engines.
http://www.toysteambible.org/ This site's goal it to have pictures and information about as many
toy steam engines as possible and over time become a source of
authoritative reference material.
This website was created by members of
The Unofficial Mamod And Other Model Steam Forum.
http://yankeetown.com/donsteam/ This site is set up by Don and shows his wide and varied collection of store bought, as well as hand made steam engines and accessories. He is especially strong in the Emipire area and has written a great book detailing their history which he sells, as well as reproduction Empire knobs, whistle ends, and smoke stacks. I emailed him about the parts from his website, but I now see he has some on e-bay as well.
