As an old farm boy, these bring back memories. We had mostly International Harvestor equipment, but as a boy, I would also help out on my now Father-in-laws farm. I always seemed to draw the Fordson, which was on steel, not rubber. Great memories from the 40's.
My first SLR was a Retina Reflex S. My Kodachrome slides from that are still sharp as can be. The Schneider lenses were great. Took a while to get used to the view blacking out with the non-auto return mirror, but I did like the camera.
