I used to work in a building that had housed a printing company for many decades until it abruptly shut down.. They left behind some sort of camera like that, probably around 4/5ths the size of the one pictured. The lens traveled on rails to focus, and rolled very smoothly.
It took up a fair amount of space, but it was mounted in an out-of-the-way location, so we didn't bother removing it.
I lived up 16 flights of stairs my freshman year in college. The building did not have enough elevators to begin with, but often some were out of service. The unwritten rule was that at peak times (headed down for breakfast/lunch/dinner/morning classes, headed up 10:45 to 1, and after dinner), it was ok to verbally harass anybody who lived below the 8th floor who attempted to ride the elevator.
Even though I lived high enough to ride, it was still faster for me to take the stairs in the morning, and when I came back from classes around noon, carrying a backpack full of textbooks and punchcards.
Of course, back then I was a fit teen and not a guy who could stand to lose a few pounds, 1906 San Fracisco probably had fewer computer geeks and (percentage-wise) more blue-collar workers than they do today.
Happy Star Wars Day.
Happy Pi day.

I suppose you aren't the type of guy who gives it 110% on a regular basis.
What's the safety issue? The ground is one of the 7 pins, and the housing (not necessarily the bracket) is typically plastic. I have one that's held on by a zip tie, for probably a decade now.
Cool article. I never heard of the guy, but apparently I like his work. The motorcycle in the second picture is identical (except for condition) to my first motor vehicle. I was in 6th grade, and a kid in my class had a motorcycle (Bultaco, BTW), and I somehow convinced my dad I needed one, too. Amazingly, not only did he say yes, but for $100 I ended up with what was certainly one of the best power-to-weight 100 cc bikes.
