After Johns sale last year, he shut down the website, but put the bulk of it back up if you can direct link to various pages, the front page though is dead. http://heidertractors.com/Catalogs.htm
should get you back in.
I will send you an email, I run http://RockIslandPlowCo.com
which covers the Rock Island Plow company and the Heider Tractor line. I cover some of the company history for Heider, but it is mostly pre 1916 when they sold the tractor company to Rock Island. We have a couple of RI Heider tractors and a coaster wagon, I have a brochure for the coaster wagons as well. If your interested in anything specific I can see what I have, but most of it is tractor related and from the RIPC days. if your interested, I can also post some pictures from Johns sale, he had a few things from the factory and later products.
