What I have is 'The Golden Book of the Rolleiflex', '4th-7th Thousand', by 'Dr. Walther Heering Verlag, Harzburg 1936'. This is in English. It is not a technical book, but rather a book of photos taken by the Rolleiflex. There are several pages of text about "The World-wide Success of the Rolleiflex" and four pages of photos from the Franke & Heidecke factory, The first photo shows the front of the factory flying two of the NS German flags. Interestingly, the front of the factory shows "Franke & Heidecke" and "Rolleiflex, Heidoscop, Rolleidoscop" as lettering on the wall. The description below describes the factory as being 385 ft. x 62 ft. with 450 people. The text reads that 200,000 cameras have been sent to "all parts of the world". To me, 1936 is of particular interest because it is my birth year.

In the Foreward, Heering makes note of the updates to the prior edition such as excluding many of the "pretty pictures" and the addition of complete Rolleicord user instructions.

(Mine is the 11th to 15th Thousand, published in June of 1933). I have been wondering if perhaps this was the first book published about the Rolleiflex. I also have the English translation published in 1934 and distributed by Burleigh Brooks, who was probably the first U.S. distributor of the Rolleiflex. Any comments on Pre WWII Rollei books would be appreciated. Thanks…Maurice
