You got an early non MLU model from the first few years of production, and a later non MLU version, from a year or so prior to the MLU cameras coming out. I am not entirely sure of the dates, I think the 6x7 first came out in the very early 1970s, and they added MLU about 6 years later. William Robb - This message is from the Pentax-Discuss Mail List.
