These sturdy fans were made in Germany around 1905-10 and patented in six countries, although they were sold primarily for use in hot climates like colonial India and in South America where most survivors have been found. The powerful spring motor runs the fan at 600 rpm for 45 minutes on a full wind; they produce a gentle breeze (as long as you're within 2 ft (60 cm)!
Update: after sleeving the front bearing and straightening the blade shaft it will now run for over an hour, although you won't get much cooling out of the last 15 minutes or so.
