Looking for case parts for a Gerster clock

I have a clock that has been handed down to me through my great- grand parents. It is a Gerster clock made by the E.N.Welch Spring Co. as the label on the back says.

I have taken it to a clock store were I was told it would cost $400.00 to $500.00 to begin repairs on it.

Unfortunatly, I am not able to afford that as much as I would like to. I inquired how to clean the case of the clock and was advised to use lemon oil on it. Can you confirm because I don't want to put anything on it that would damage the case. The case is in good shape but has a piece missing and would like to at least try to find a replacement part. (I'm sure not going to be easy)

Any help on how I should try to locate any pieces for this clock would helpful.I am also missing the brass ring that goes in the center of the dial. Even if the clock can not be repaired I still display this piece every day and would like to have the case look good .

Thank you, Regan
