With thanks to Winston Sinclair for alerting me to this one-- I had a search on
ebay in Philatelic Literature, but not in books-- this one never showed up in the Philatelic Literature area.
Best price I've seen-- I used the "buy it now", but probably should have put the same bid on the book and maybe would have paid less for it. You can find it from the philatelic literature dealers in the $200 range and up (and this is the deluxe edition with slip cover and gold pages), but the "buy it now" at $145 was a really nice price.
The Neinken book was published in 1972, and a lot of it is the same as the Ashbrook book from 1938. I was most interested to read and understand the discoveries that happened since the original Ashbrook 1c book-- and mostly how they figured out that the Type Va stamps were from plate 5, not plate 6 as in Ashbrook.
It is a shame that these older, out of print references aren't readily available at prices that the average collector or philatelist can afford. But it's become really obvious to me that if one is to understand the 1c Franklin issue, BOTH of these books are an absolute must.
So, I've got some major study and learning to do! This issue is absolutely fascinating, and very affordable-- you can spend a lifetime collecting just US #24, which can be bought for as little as a few bucks apiece on eBay-- but again, to understand the differences in the plates and positions, the references are very necessary.
Here is a picture of the book (taken with my iPhone, so the book is on it's side:

Thanks again to Winston, and to Art Launier for piquing my interest in this issue-- Ray
