First, let me say that I am a newbie that knows little about clocks. I was recently given a westminster chime mantle clock which keeps time perfectly. It chimes on the 1/4, 1/2 3/4 and hour ok but the problem is that the number of strikes on the hour is erratic. For eg. at 3 o'clock it may strike four or five times. At 11 o'clock one or 5 times. there is no set pattern it just seems to strike at random. I have tried to move the hour hand to correspond to the number of strikes but with no success. I would be most grateful if someone could help me to solve this problem. I do not know the clocker makers name.
