I just got a copy and find myself refering to it *constantly*. My only regret is that I didn't know about its value several years ago. In addition to complete history and descriptons of *every* Nikon product ever made, it includes the list of serial numbers Scott asked about. Got mine at Amazon.com. The reason I'm posting this to the group instead of directly to Scott is to thank Moose for this valuable book by spreading the word. Dan Dresner
