Thomas' car parts book

Several weeks ago Thomas brought home a book that Pa-Pa had given him. It's a book full of everything one could want to completely rebuild an older car just like Pa-Pa's. Thomas loves this book. Every morning begins with a look through the book and he'll seriously study many of the pages. He looks at old brochures and books available for sale (as in the above photos) and exclaims with delight "Pa-Pa's car!!" when he sees a cover with the same car. He looks at page after page of car parts he recognizes such as bumpers, lights and wheels. He'll read the book with one of us and repeat words that we say like carburetor or manifold. I don't even know what those are, but I'm sure Thomas will figure out what they are and what they do long before I do.
