[Leica] Old stuff

[lrzeitlin at aol.com]

 The discussion and photos of the Babbage Differential Engine of a couple of weeks ago prompted me to dredge the pictured 50+ year old artifacts from the bottom drawers of my desk. Many more are still interred there. All still work as well as they did when they were new. No batteries are required. Bear in mind that most of the bridges, all of the WW2 airplanes, and all Leica lenses prior to the Summicron were designed using slide rules and mechanical calculators. Will the Leica SL still work in half a century?
