Thanks, folks, you guys are great. I'll look into those books. I'm a reasonably good mechanic and the car I'm getting is in excellent condition. My model A had sufficient peculiarities (like all cars) that a good reference can save much time and money. You'll no doubt be seeing some questions from me in the near future.
I did find a beat-up copy of the Page book at AbeBooks for $15, so ordered that.
