This antique Seth Thomas 8 day time and strike wall clock dates to 1910 or earlier - this style with brass buttons appeared in the 1880s. It's known as an "Office" Octagon Drop model, measuring 14" wide by 22 inches long. It has an unusual reverse painted tablet - the glass door that accesses the pendulum. The key is present, the striker gongs the appropriate number of times at the top of each hour, and the clock does work, but I've found it hard to keep the pendulum moving. I'm sure it just needs a simple adjustment but I'm not competent enough to mess with it, or to try removing the back panel.
The metal dial has roman numerals. There is some faint age crazing to the face finish and fading of the minute marks between 9 and 10. The reverse painted glass door or tablet at the bottom has a red and green begonia decoration. It appears the black paint may have been touched up on the back side of the door. The wood case has gold trim and decorative brass rosettes. The large glass clock face door closes securely, but the tablet has a little gap on one side when closed. The wood finish is very good, but the back panel is a different type of wood and may not be original (the metal hanger at the top is original however). There is some writing inside at the bottom: a possible stock number or date code "61092" preceded by the letters LH or CH, and also "POE 466-0300" in pencil.
Found inside the clock with the key was a scrap of paper naming the owners, Tom and Lillian Rock of Murphy Idaho. Thomas C. Rock was born in 1903 and died in 1966; Lillian was born in 1896.
