That's indeed a rare avis, as there seems to be more of the Mercedes D.III OHC engine's extant nowadays. It's amazing that they were able to find an old one with the plywood formers still usable for the rebuild, been watching this plane come slowly together since I first discovered that Memorial Flight was bringing old WWI planes back to life.
I sure would love to see those rocker arms in WOFF as well as a LVG C.VI.
Targetware's Richthofen's Skies LVG had the Benz with working rockers. But because of sim engine and propeller timing issues, it didn't actually follow a proper inline 6's valve timing. It's hell to code valve mechanism animations, my having done an RAF-1a's rockers. and that's just the exhaust timing.
