The info provided earlier came from the 1929-1950 Master Parts Catalog. A later version of this catalog is available online at oldirononline.com. Look under the parts catalogs section. Copies of various editions are available from a variety of vendors, as reprints. They show up for sale occasionally on the auction sites and at swap meets as well.
