Series 210 Roller-Tilt Balance Quote

Question

The balance case is white plastic, and the rotating cog that holds the window is light blue plastic. I don't see a stamp on the coil. The only number is PAT5,353,548.

I'm afraid I don't know what you have. This is a photo identification service, so we will require a clear photo of the hardware in question before we can recommend a match.

Note that we may ask for more photos afterwards, but I need to know what to ask for first.
