It's nice to have OEM parts and manuals but these items are not as rare as you might believe. The 2N battery cover was added when they changed the snap-in battery door, an original item that IS RARE, to the hinged battery/gas tank access door. Dennis Carpenter repops the 2N battery cover new, exact-as-original. The early snap-in covers were prone to falling out and lost and the later 2N covers were often left off and tossed away or left in the barn. The DEARBORN manuals are a dime a dozen. DEARBORN MOTORS, was incorporated in January 1947 as the new Ford tractor distributor for the 8N Tractor Model, released in July, 1947, and all implements thereafter. Original used DEARBORN manuals, as well as a few illegally copied newer clones, can be found on ebay all the time.
