This is from my late husband's storage room. I know very little about clocks. This is what I can tell you.When I wind the clock, the pendulum moves and both hands move accordingly. The hummers try to hit the rods to play Westminster chime note but it is doesn't sound right. It also sounds dull. (One of the hammer doesn't touch the rod.) Three of the five rods seems to be replaced. (The color is different.) It looks pretty good outside. Please check photos for details....r>Measurement Base part 25 1/2’ x 6 1/2’ Height 6 1/2’Diameter of the clock 8 1/4’ (Frame) 6 3/4 (Inside window)
