Hi paddleducks,
have a look at this
www.trivapor.ch it is a club who works on the rebuild of the steamer Neuchatel, the ship is build in 1912 retired in 1969 and converted into a restaurant. They have bought a two cylinder engine from the Bavarian PS Ludwig Fessler. Unfortunately for you the site is only in france and german, but a few photos from the ship and the engine.
Regards
