For those of you who have a copy of this catalog and have found different new pages for it and wonder why, it is because it was issued once in 1951 and had many items that would help the dealers with added pages sent for adding to it through the next couple of years. It is divided into four sections with items that the dealers could order to help with sales. Literature, Advertising and Direct mail items, Facilities including signs, parts department display fixtures, decals and uniforms were nicely illustrated with color sheets. Specialties like model cars, pen desk sets, pencils and matches, Kalacloths, tee shirts and Zippo lighter were all included in that section. Selling System and Training Material was the final section and it included such subjects as facts books and paper supplies to help the dealer or salesman keep records and to help them be more efficient. In January of 1953 the factory sent the dealers a package of all new sheets and dividers and asked the dealers to remove the old sheets and dividers and destroy them and install the new ones in their place and made the hard bound black and yellow binders available for $1.00 if needed. Complete binders are rarely found as the individual pages bring good money at swap meets and on eBay. I recently found an envelope with the new instructions and pages from 1953 and started a second binder and later found a letter to the dealers with four new sheets to be added and with the added note that more would be coming in the future but I have never seen anything for other than up through the 1953 years. These binders are 1 3/4" inches thick, notebook size, and are not to be confused with the accessory catalog book that has hundreds of illustrated pages describing accessories as they were announced starting in 1947. The Sales Aid Catalog does have interesting information and illustrations on dealer decorations, signs and clocks etc.
