The patent number 171659 was issued in 1906 for a feature of the striking mechanism...and the patent was used to about 1922 per what John Hubby has written. Note that there is a serial number under that oblong plate below all the logos. If you remove the plate, the serial number will be helpful for narrowing in on a manufacture period.
Thanks again Kurt what a great help you have been!
This clock came with a floor standing case, looks a bit home made is there somewhere on here where i can get a few pointers try to put it all together to see if actually works?
