I don't have any diazo printing equipment (Bruning or otherwise) or even much information on the subject. The last time I was close to a diazo whiteprint machine was in drafting class in Junior High School. But I happened to borrow the following two manuals in a box of miscellaneous stuff, and they seemed worth preserving digitally.
Bruning Copyflex 200 Instructions
Bruning Copyflex Instruction Manual for Model 200. (Mount Prospect, IL: Charles Bruning Company, Inc., [by 1960]). No date, but contains a "Lamp Failure Report Card" dated "7/5/60", for machine serial number 200381.
Thanks are due to Jenny Addison, Prop. of Lock and Key Press, for making this material available.
Bruning Copyflex 300 Instructions
[Bruning Copyflex] Model 300 Instructions and Parts List. (Mount Prospect, IL: Charles Bruning Company, Inc.) No date, but drawing on page P12 was revised "7/62".
Thanks are due to Jenny Addison, Prop. of Lock and Key Press, for making this material available.
Both Bruning Copyflex manuals reprinted here were published in the United States without copyright notice at a time when such notice was required to secure copyright. They therefore passed into the public domain upon initial publication. The digital reprints of them here remain in the public domain.
The Charles Bruning Company was acquired by The Océ Group (of the Netherlands) in 1991. A 2010 search of the USPTO records indicated that the trademark registrations for both "Bruning" (in this context) and "Copyflex" had expired.
