You're welcome!

I think Iíll strip it completely, wash all parts, apart from the motor as you suggest. Them reassemble with oiling the pivot points with a tiny drop of engine oil on each and some sewing machine on the rotor pivot as you say.

Can I ask, is sewing machine oil better than clock oil for the rotor on this type of clock?
Yes. Clock oil is made so it doesn't "run" - i.e. it needs to stay in the same place, whereas the rotor in a clock needs oil that can reach all parts of the bronze bearing and many of these are sintered - the bronze is made from a powder and acts a bit like a sponge.

Thanks, Paul, for the accolade!

Thanks again for your valuable knowledge!

One last question before I get on and strip the movement down. Is there a way to establish the age of this movement? Maybe from the markings shown in the photos? It would be great to give the owner a little more info on the clock when I return it to them.
