I have a copy which I got cheap at the Martin factory shop due to a printing or binding error--it had some pages missing, so they stuck in photocopies of the missing pages and sold it to me for five bucks. (in 1983).:)> Maybee it's extra collectible. But I'm keeping it. (It has the all-important serial-number/year list, as well as production totals for every year through the late 70's)
Fascinating stuff for us devotees.
By the way, my O-18 sounds and plays so great now with new Elixirs on it, I'm playing it as much as I am the Lowden.
