Pickups, Windings and Magnets

This book is full of interesting historical stuff and would clearly be of great interest to collectors. As a technician, I was a little disappointed that so little attention was given to tech details. Would like to see a text devoted almost entirely to schematics, oscilloscope patterns, flux densities etc. This would be of little use to musicians, I guess, but would be really helpful technical types like me who do the design work.
