A CLOCKS mag bibliography for 1978-1998 for example shows 40 citations to W&H or W. In the standard reference _Die Uhrenmacher der hohen Schwarzwaldes und ihre Werke_ by Gerd Bender, for instance, there's a 25-page section on the W&H clan. That's called "Brotherhood" ( Yes Kathy, etal - sisters are inklooded) How 'bout it DL? 82E, 90E; however I see no illustrations of these particular movements. If Kochmann is correct in his European Trademark book the "M Winterhalder & Hofmeier G. There are several refs/articles in the _NAWCC Bulletin_ and in other journals and magazines. All of these sources -- and there are others -- are available through the Library & Research Center. Perhaps we could benefit - learn something - from your bad experience.Even his grandfather Nikolaus Winterhalder (1710-1743) made quality Black Forest clocks with wooden cogs and weights from stones.
However, a movement signed by one maker may have been placed in a case made by another - a practice usually termed a "marriage." A clock case made in one century might even have a movement made fifty or a hundred years later.Below is a sampling of some of the most common clock makers marks you may come across.DLJ, You really need to post some pictures of both the case and the movement. I don't think that the numbers that you mentioned will help us much. The style of the case and the movement will greatly help in any identification. So -- briefly -- Hans Winterhalder was the son of Johannes Winterhalder (1866-1935) son of Anton Winterhalder sen. Hans gives up the W&H connection and founds his own firm, first called "Hausuhrenfabrik Winterhalder KG" and then (11 April 1925) "H.

(1838-1912) who was one of the 7 children (4 sons) of Matthus Winterhalder (1799-1863), the co-founder of the firm Winterhalder & Hofmeier. Further economic problems led to the firm becoming stock based in 1928, with three German firms (Kienzle, Mauthe, and Junghans) holding a majority of the stock. For whatever reason, HWN and Hawina *are* frequently confused with the firm Winterhalder & Hofmeier.
Linus Winterhalder died in 1932, and Winterhalder & Hofmeier had to stop production in 1933 due to lack of liquidity.
On June 2, 1937 the company was stroken off the commercial register.
By the time we get to the 3rd generation, your Hans' Dad's, W&H consists of 5 "part-firms," one of them being Johannes Winterhalder, Neustadt (in Baden). After the Crash, things worsened, the firm was liquidated, Junghans took it over, but soon shut it down completely. For example, in a standard US reference, Tran Duy Ly's _Longcase Clocks and Standing Regulators_ an HWN movement (stamped for the Colonial Manufacturing Company) is identified as a Winterhalder & Hofmeier.
Then in 1930 Hans "emigrated to America and founded there still again his own clock factory" but also had little luck.
