Otto Kolan's BMW special from 1949. Otto first appears in this car in mid '49, then transfers to a Swedish Effyh for the later part of 1950 and the first half of 1951, and back to the OK to take sixth in the West German Championship. He continues with the OK for a rather disappointing 1952 season before buying a Cooper Mk IV for 1953.
