The smaller tiller is a Simar C2J and the other one is a Simar C80. The C2J was imported in the mid to late '30's. I have no information on the C80, just the tiller. It has a 36" cut and is over 800 pounds in weight. The engine is either a 10 h.p. or 12 h.p. 2 cycle. By contrast the C2J is only a 14" tiller with a 2 1/2 h.p. engine and is only 240 pounds. It sold new in 1935 for $283.00 f.o.b. N.Y.
