Hello, I am appraising a Herschede Pattern number 121, which has three numbers on the back, “6,” “121” which is obviously the patter number, and “408,” which I think is the serial number. However, in the book Longcase Clocks And Standing Regulators, Part 1: Machine Made Clocks by Tran Duy Ly it says it was made in 1920. However, in the serial number guide, it shows this to have been made in 1913, if the 408 number is the serial number. And, to add confusion to all of this for me, I have a document saying the clock was actually made in December, 1915. So, am I correct about this actually being from 1913 based on the serial number chart, and if so, what is the discrepancy? Next, what does the number 6 represent? Finally, what would be a proper, professional, detailed description for this clock in general, the movement/works and case within the horological industry? Thank you for your time and assistance.
