Well, since the topic has shifted to slide rules...I've got a collection. I'm in my 50s and probably the last generation to have learned them in grade school. My dad is 92 and an engineer. He's already given me his ivory covered Picket. I'm a (inactive) private pilot, so I've got an E6b circular flight computer.
I've got a collection of various other special purpose circular and linear calculators for everything from construction to celestial navigation, but my special one is the one my dad picked up while he worked for IBM inside the Pentagon during the early 1960s. It's a nuclear bomb blast damage calculator. Yeah, really. A guy my age who grew up in uber-liberal Berkeley, CA thought it was a joke item, but there was a time in this country when many war planners and scientists had one in their desk and used it often.
Once dad gave me this there was only one thing to do; find its mate Online I found and bought the same model radiation decay calculator Dr. Strangelove used in the movie to determine how long we needed to stay in the mine shafts. It's in a box somewhere so no picture, but here's something about it.

I just added this to my list of things I will build as soon as I get the time by being laid off or kicked out by the wife.
