Hello,I am looking for a very nice unbuilt Renwal Visible Wankel Rotary Engine for my nephew and his fellow Scouts. I would prefer it not to be built so I may build it with them to explain the procedures, principles, and mechanical engineering incorporated into the classic Rotary Engines.I would also be interested in any of Renwal's other Automobile engines, The V-8, The In-line 4, or the Visible Automobile Chassis. Even the Radial Airplane Engine as well.If you have one of these or know someone that has one they would like to part with, please send me your contact info and I will get back to you asap.I will travel to most anywhere in Texas for the right model.May consider one that is partially built.RegardsCharles
