I gave my wife a hand-crank sewing machine from Germany, probably manufactured after the turn of the 20th century. she made that identification right after unwrapping it on late Christmas Eve. http://www.retrotechnology.com/herbs_stuff/german_sewing.jpg She's very knowledgeable about pre-1950's sewing machines; I also have a clue. And I have no doubt these are "technology". They are mechanical devices with precision parts which perform mechanical computations.
It might be possible to hook it to a computer and automate it!
