Query: Specifications, not Nostalgia

If you're looking for a trip down memory lane this book is not the choice. I was expecting a coffee table book with pictures of vintage snowmobiles. Instead, it is repackaged period shop manuals. That's great if you own a vintage sled and need to know specs, it's probably invaluable for that purpose. There is no description for the book, so my fault for assuming (or hoping) it would have color period pictures - which it does not.
