German right angle gear drive?

[berman]

I am seeking a photo or drawing of the right angle gear drive connected to the engine as used on aircraft such as the Mises bomber, Siemens Schuckert bomber, and Oertz flying boats. I read on a previous post (Kees Korner #7) that geared engines, as used on the Zeppelin Staaken, had a 400mm cast iron flywheel as the propeller rpm was geared down. I assume that this also might be the case with aircraft with engines located in the fuselage driving propellers though a pair of right angle gear assemblies and shafts. I am researching an Oertz W6 flying boat that had a pair of Maybach MB.IV 240hp engines driving two 3200mm Lorenz propellers. Thank you for your assistance.
