No, not the famous last word of Charles Foster Kane but rather Rosebud’s WWI and Early Aviation Image Archive.
Actually the website of Rod Filan and maintained by “Rosebud”, it was a treasure trove of downloadable early aviation pictures from the early 1900s through the end of WWI. I hadn’t visited in a while and when I tried to several months ago (I needed new background pics for the work computer) my bookmark didn’t work anymore. My friend Mr Google couldn’t tell me what happened nor did I find any answers at the next best place I could think of for information The Aerodrome.
I still don’t know why it went away, but archive.org and their Wayback Machine found a version that’s still active: Rosebud’s WWI and Early Aviation Image Archive.
It’s still well worth a visit…

A follow up to the Daimler-Benz DB 602 (LOF-2) engine
By William Pearce
Daimler-Benz was formed in 1926 with the merger of Daimler Motoren Gesellschaft and Benz & Cie. Prior to their merger, both companies produced aircraft engines under the respective names Mercedes and Benz. After the merger, the Daimler-Benz name was used mostly for aircraft engines, and the Mercedes-Benz name was used mostly for automobile production. However, both names were regularly applied to marine engines. For clarity in this article, the name Daimler-Benz will refer to aircraft engines, and the name Mercedes-Benz will refer to marine engines.
As Germany began its rearmament campaign in the 1930s, high-performance marine diesel engines were needed to power various motorboats. The Kriegsmarine (German Navy) turned to Mercedes-Benz to supply a series of high-speed diesel engines. These engines were part of the MB 500 series of engines that were based on the Daimler-Benz DB 602 (LOF-2) engine developed to power the LZ 129 Hindenburg and LZ 130 Graf Zeppelin II airships. The 500 series diesel engines were four-stroke, water-cooled, and utilized a “V” cylinder arrangement.

Around 1930, Daimler-Benz* developed the F-2 engine, initially intended for aviation use. The F-2 was a 60 degree, supercharged, V-12 engine with individual cylinders and overhead camshafts. The engine had a 6.50 in (165 mm) bore and an 8.27 in (210 mm) stroke. The F-2’s total displacement was 3,288 cu in (53.88 L), and it had a compression ratio of 6.0 to 1. The engine produced 800 hp (597 kW) at 1,500 rpm and 1,000 hp (746 kW) at 1,700 rpm. The engine was available with either direct drive or a .51 gear reduction, and weighed around 1,725 lb (782 kg). It is unlikely that the Daimler-Benz F-2 powered any aircraft, but it was used in a few speed boats.
