I've been on the documentation hunt once again and added the following to my list:
-Ludw. Loewe & Cie actiengesellschaft Berlin 1869 - 1929 (Loewe company history, published by the company itself in 1930).
-Die Pistole 06/29 1944, Swiss instruction booklet.
-Die Pistolen 9mm Pist. 49, 7,65 mm Pist. 06/29, 1962, Swiss instruction booklet.
-Gunther Quandt erzahlt sein Leben, The memoirs of Gunther Quandt, written while he was interned after 1945, published by his sons in 1961.
Some short background info:
DWM, FN and Mauser were part of the Loewe concern from 1896 until 1928 (FN shares lost as damages payment to Belgium in 1918).
The Quandt group took a majority interest in the DWM and Mauser companies in 1928.
Several members of the Loewe Supervisory Board were certainly interesting:
1897 - 1903. Max von Duttenhofer. Founder of RWS.
1901 - 1903. Sigmund Loewe (or Siegmund). Brother of Ludwig and Isidor, one time manager at Maxim-Nordenfelt and Vickers, Sons & Maxim.
1904 - 1906. Albert Vickers. One of the Vickers brothers. Took over seat of Siegmund Loewe after his Death in 1904.
1911 - 1929. Paul von Gontard. Managing director of DWM.
This again shows the direct links between Vickers and DWM / Loewe.
