I wasnt sure which category to list this because there was not one for clocks. I am trying to find out any info on this clock. I see some are 8 day clocks, I am not sure if this is one. I am not familar with clocks, so How would I find out if this works. Also the pendulum is marked 1839. Is that a year? or a product number marking. Thank you much for your help. The glass on the fron is beautifully bezelled.
