..............I'm not sure if this is of any interest to anyone (or even if this should be posted on this thread) but I've acquired a soft-back A4 book called "Polaroid Black & White Land Films - A Guide" by Polaroid Instant Photography. It was published in 1983 by Focal Press. It's in extremely good condition, despite being almost 30 years old.
The book contains 48 pages loaded with information, history and prints from the 40, 50, 80, 100, 500 and 600 series films together with 20 pages of technical data sheets on types 667, 107c, 107, 084, 87, 57, 47, 552, 42, 665, 55, 612, 611, 51, 146, 46 films.
I've had a good read through it but, as I'm not really a Polaroid aficionado, it's not really "up my strasse", so to speak. However, it would almost certainly be of great interest to anyone who wants to learn more about Polaroid mono films.
So, if any serious Polaroid user / fan wants it, I'll send it to them gladly (anywhere in the world) as I'd like to see it go to a good home. I'll send it, free of charge, to the first person to send me a PM asking for it. All I ask is that only real, techie fans of Polaroid PM me as this isn't just a book of photos - it's a proper reference book.
All the best. Paul.
