Greetings … I recently acquired a Colonial of Zeeland grandfather clock. Unfortunately, there is no key to open the cabinet, so I have no serial numbers. The only identifying marks are stamped on the back of the case … 9504 574 Made in U.S.A. I will post photographs as soon as I can, but anxious to get a head-start. I can open the top of the cabinet, so I believe the it has a Urgos movement. Any information would be appreciated.
