It is very time consuming to look up a clock by its model name or number. There were literally thousands of Seth Thomas models made over their almost 200 year history.
If possible, a picture, or description of the clock will go a long way to help.
Thanks for posting. If you can add more information, you can post it as a comment below and I will see it. If you want to post a picture, do it in a brand new posting and in the story box reference it to this post....(curious about seth thomas clock) so I know who posted it.
