1920 CHELSEA SHIPS BELL CLOCK REGISTERED TO GEORGE E BUTLER of SAN FRANCISCO. This was given to me by my step dad which was given to him by his father. I'm not sure the back ground of how he ended up with it but it still works and the chimes work and sound beautiful! I think my dad cleaned it up, it looks like he did! I wanted to shine it up but I'm not sure if you're supposed to or not! I called to find out some info on it with the serial number and all they told me was it was r...egistered to George E Butler back in 1920. It's a wonderful clock and it has the original key also.
