I just realized that both the julian and Adams-Farwell cars used horizontally oriented rotary engines. I've never seen a Julian, but for years, there was a green Adams-Farwell in the Reno car museum. BTW, the Ruxton was a very expensive 1920s era FWD. Hmm, would it be hard to design a watercooled rotary engine? Just imangine the spinning water jackets! ron 65,66
