Hyde Brothers Booksellers in Ft.Wayne,Indiana has a 1936 last copyright date for $25.00 + postage . Still has T information. A wealth of mechanical knowledge. 260.424.0197.
I found an original Dykes 1915 at Stowe and the fellow wouldn't budge off $150.00. He stated the obvious, "try to find another one". As it were the gauntlet was so thrown. I bought a copy of Dykes from 1915 from Amazon books. They have reprinted same and its readily available for a reasonable price. I'm not a book collector but Dykes is the best friend if you need a workshop manual. No T guy should be without one.
Have several from the model T Era any interest shoot me a message I dig them out for the priming date
They show up on T-bay often.
You can read them for FREE at books.google.com
The last one I got was 2 years ago at a garage sale with 4 other hard back books for 5.00, it did have a broken spine so it will become a garage book but can't beat the price.
