Lot of 2 books. I do not see a date on the NY book. That one is in quite rough shape with binding and wear issues. Also there could have been some pages torn out of the back as shown. Does include a foldable diagram at the back. PRR book in better shape and dated 1935 and it also has a fold out at the back. But it too is well used.
This product would be a great fit for railroad enthusiasts looking to preserve and maintain their vintage railroad equipment using authentic instructions and compatible brakes.
