Heinz Melkus built a series of racing cars through the late '50s and '60s.
This is the first, from 1956, which was heavily influenced by the Cooper Mk VIII but used a De Dion setup at the rear.
A JAP engine was used, though quite how he obtained this in East Germany is a mystery. At some point he seems to have replaced this, with what we do not know, and the car is sometimes referred to as Melkus Post-JAP.
Heinz finished third in the East German National Championship in 1956 and '57 and won in 1958, the last full year.
