Very first 35mm was a Tower from Sears Roebuck and Company. Everything was manual and it still works like the day I got it in 1963. My second was an SLR that I got in 1965: Zeiss Ikon Contaflex Super with several Pro-Tessars besides the standard: 35mm, 85mm, 135mm: along with come close-up attachments. Some of you may know that it didn't have an instant return mirror, so the viewfinder went blank at the time of exposure. The mirror came back in place when you advanced the film to the next frame. It was a great kit and everything still works, including the selenium cell built-in meter! I use it several times a year just for kicks.
