That's a very sloppy article right there. The lede is ridiculous, saying it is "still running... since 1864" which is contradicted in the body. The mechanism that actually powers it, not mentioned in the lede for some reason, but instead we are briefly led to believe that it was powered by a wind-up mechanism that hasn't been touched.<p>Lastly, a rather pitiful assortment of references. This could be a better article if someone cared enough.
