There is a very similar title, "Summary of German (Rheinmetall) Electric Fuzes", produced in loose leaf format by the Research Department Woolwich and was amended throughout the war. It shows the electrical circuits of the fuzes. In June 1944 the title was changed to "Summary of German Aircraft Bomb Fuzes". From recollection the pages on a fuze show an electrical circuit diagram, markings, colour, how it works, differences between the models, etc. I'm not sure if I still have a photocopy of one of the editions but I will look (not an easy task) if someone doesn't come up with the goods in the next week or so.
