Hammer

Steam hammer in operation at Westinghouse Electric, 1904. Edison film.
Compare with a recent video from China:


Chinese smiths allegedly forge a LARGE flange on the street
Hit it again, Mac. No, I don't know why the word "allegedly" is in the title. Maybe somebody learned a new word.

I posted the Chinese video once before, but then it vanished and I replaced it with more modest forging, though it looks like the same hammer.
