I doubt very much that it's a Lynx 1000. The Lynx 1000 had a selenium meter cell on the upper left side (lens pointing at you) and didn't need a battery. It was the first of the series and wasn't marked IC which stood for integrated circuits, which came about 7-8 years after the Lynx 1000 which was introduced in 1959. The first 35's to use integrated circuits were the Lynx 14E and the Lynx 5000E. The Lynx 5000E had the same spec as the original 1000 except for a CDS cell for the light meter powered by a PX640 battery and of course, the integrated circuits. My guess is that you have a 5000E.
