Grandfather clock not working?
We have an old British antique grandfather pendulum clock dated 1938. I understand the order in which the weights are ordered but when they are set on and the pendulum is swung the pendulum only swings for about 10 or 15 minutes. Could someone remedy and should I get it looked at by a professional?
It also has marked on the mechanism base - '999 'M 'W or else it is M, W, 666, what does that mean.
