I'm not a clock collector. This one was found in a local storage sale. I don't know the maker but from what I found online, it may be a "Chelsea" or a "Seth Thomas".? I borrowed a key to see if it worked and it does and seems to keep the correct time. If you are a collector hopefully you will know just what you are looking at here. I have a video of it running but can't figure out how to add it. Clock is double boxed and well padded.
