This Leica M3 was built about the time I was born, 1958. It still has all the original parts. So do I.
This morning I ran my first roll of film through the camera, some expired Walgreen's "Studio 35" 200 ASA house brand film I acquired off ebay last year. It cost me 25 cents a roll. I would say this 50 year old camera and the 25 cent film did pretty well together.
