Mike, My guess is that your clock is a Gustav Becker clock. Unfortunately, there arent' any serial numbers listed for 1927 and beyond. If you Google: Gustav Becker Grandfather clock, you will see other clocks very similar to yours. They're well made clocks and nicely designed. Good luck with it. Mark B.
