Lawson
The Lawson Engineering Co of Bishops Stortford (est. 1969) built LE sidecars and the Zorplan Shopper tricycle.
The LE Sports Sidecar was manufactured from 1976 to 1983. A post suggests that an LE was mated to a Silk two-stroke twin.
The Zorplan Shopper, a tricycle based on the Puch Maxi, was sold in kit form from 1978 to 1980 and possibly later.
