His book did not date the introduction of each type and did not cover a LOT of the eyepieces available today.
He did talk about many of the eyepieces available and give a small discussion of each type, as well as, of course, some
generic information about eyepieces.
My house is under construction right now, but some time in the next couple weeks I'll dig out from under and rescue my copy.
Send me your address in a private message and I'll gladly send you my copy once I find it again (might be a month).
