I keep seeing the wing logo for Kienzle clocks in other parts of the forum. But I've never seen that logo on a 400-day clock. None of mine have that kind of logo. Kienzle was in the 400-day clock business from something like 1910-ish to 1929...I believe they made other clocks before that. Any history there to the use of the logo? Kurt
Kurt, Kienzle had a few varieties of the "winged clock" trademark, one of the earliest of which was from 1889, IIRC. I do not know why Kienzle did not mark their 400 day movements as they did their other clocks. Regards.
