I have the 1947-1954 Truck Factory Assembly Manual. Some of the drawings give specific models, such as "Models 3100 - 3600 - 3800 - etc" but other drawings say "Models - All RD."

What's RD stand for? Thanks!!

Also is there an index somewhere so you don't have to go through every page, one by one, to find the drawing you're looking for? Thanks, again.
