1973 "ERC Independent Iso" #253 by Jan Forsgren

This design, built by both Jan Forsgren and Bjarne Lilliendahl, was the most common chassis in Sweden for several years. JF started his cooperation with BL as "Fool Production", but in mid '73 they changed the name to "ERC Products". Motor also from ERC. Note asymmetrical lead to help getting round the donut on a Kingtrack.
