Torsiondoc, your clock has a bit of history. My first data entry for this same clock was in 1996 when I was studying the Terwilliger archives that at the time belonged to Bill Ellison, the then-owner of The Horolovar Company. The data source was a letter and photos sent to Charles Terwilliger in 1987 by a Mr. Randall. I have copies of these somewhere in my archives, will try to find them over the next few weeks. Terwilliger was founder of Horolovar and original author of The Horolovar 400-Day Clock Repair Guide. At the time, not only did the clock have a pink alabaster base but the columns and pendulum balls were laquered in a matching pink color, likely original. Unfortunately that finish has been polished away.
This clock was made near the end of 1936 based on the serial number.
The Mayer story is that Mayer, a large German jeweler and wholesaler, evidently contracted with Kundo in 1931 to make this design for them including having their name exclusively on the back plate. The design was trademarked as seen by the stamp "Ges. Gesch." (full spelling "Gesetzlich Geschutzt" which means legally protected). It turns out the trademark outlasted the deal, these clocks were made with the Mayer name only from late 1931 to late 1933. After that, Kundo evidently acquired the trademark and continued producing clocks with this design up to the end of 1939, some with no name or trademark and some with the typical "KO" or the Kieninger & Obergfell mark. All of these designs in my data have the "Ges. Gesch" stamp.
As an observation, I believe that Plate l467 has an error in that there is no serial number present. To date, I have yet to find any Mayer logo clock without a serial number, and all those made with no logo or Kundo logos prior to 1939 have a serial number.
