Welcome to the Message Board, Bluerose. Haas and Sons was a well-known manufactory of clocks. Rather than have me stumble around with imparting information, have a look at this thread, which appeared recently and has information on the company, and which, in turn, will lead you to a couple of other informative threads. Of course, others will be along to help as well, I'm sure.
If you have a picture of the clock on your computer or can put one there, it is relatively simple to upload one using the Manage Attachments function available when you post a reply or start a new thread.
