I've suddenly found an interest in the Technika III camera line, particularly the 2x3. Is there anybody out there that can direct me to info on the line--ie when they came out, how many versions, difference between them, etc? I;ve done a Google and got one page that talks about a version 5, I was more interested in what the line looked like in the late 30s and 40s. Or were they that early? Les
