Hi thank you, that is my worry that a bath in the sonicator will destroy the finish, any suggestions?Hello. This is lacquer. It may well be an original factory finish, dunno. As shellac lacquer ages it turn this 'golden' colour. Areas of the mechanism where the lacquer has degraded or never been lacquered have corroded/tarnished to dark brown. Hope you preserve the finish. It is really interesting and in my view, nice.
Thank you for the help!Yes. get some mineral spirits, white spirits or paraffin or the proprietary equivalent such as L&R No3 watch cleaning solution. Disassemble the clock, wash the components manually in a plastic tray with a natural bristle brush such as a paint brush and peg out the pivot holes. dry (in maize drying media if you have it) or just naturally and all should be ok. The brass will not be brightened but the clock and importantly the bearings will be clean. re-assemble and oil. All good. Hope this helps. You will need PPE gloves nitrile and a well-ventilated space.
