It is a German Vienna regulator clock and movement probably around 1880.
Unfortunately the movement photograph is extremely dark. It would be helpful having better photographs of both front and back. Current photograph is the back.
Some German movements makers supplied unsigned movements to other companies so it maybe difficult to identify them. Disassembling the movement might yield information.
Hello, John!I agree with Tatyana this is an unsigned Concordia, now the third one I have in my database. Key identifiers include the shape of the one-piece crutch extension, the back plate train layout, the one-piece formed upper pivot bridge, the shape and style of the hand-stamped serial numbers, and the design of the Vienna style hands. My data show it being made a bit later than Tatyana mentioned, in my case looks like early 1892.
For info, question to Tatyana: What is the highest serial number you have in your data for Concordia?
Jess and all, for information there is no known Becker movement in this period that does not have a Becker logo stamp on the back plate or a serial number with less than six or seven digits. Becker had made 1,000,000 serial numbered movements by first half 1892.Looks to me like a Becker or Jughans Vienna Regulator from Germany
Apologies, i wasn’t judging very accurately. Specifically talking case construction and style.Jess and all, for information there is no known Becker movement in this period that does not have a Becker logo stamp on the back plate or a serial number with less than six or seven digits. Becker had made 1,000,000 serial numbered movements by first half 1892.
I don't have info for Junghans but their movement designs for this period had a number of differences from the Concordia.
