I took a walk this morning near the southern end of the 17-mile escarpment west of Albuquerque that makes up the Petroglyph National Monument.
The camera was a Contaflex I. The shutter only worked about half the time, so when I got home I disassembled the thing and cleaned the shutter. I've done this about twenty times now. In spite of the problems, it is still a great favorite. I bought another recently in about the same condition, so I'll have more opportunities to learn about repairing this model.
