If you have access to the 1948 issues of Model Railroader, you'll find in the Sept. and Oct. issues the pair of articles from Joe Fischer on how he built passenger cars.
I got out my Sept and Oct 1948 issues of MR but there were no Joe Fischer articles. Then I looked in the Kalmbach online index but it doesn't list any MR articles by Joe Fischer. So I got out the paper indexes for MR and found the articles in the Sept and Oct 1949 issues of MR.
I don't have any Joe Fischer cars but I met him once or twice in George Stock's shop in Philadelphia. Joe was bringing some of his cars to George for painting.
