A British J.A.P. engine built under licence, most likely in Italy. The letters and numbers correspond with the J.A.P. engine code system.
K = 500cc
O = overhead valves
C = sports engine
Z = dry sump lubrication
85.7x85 = bore and stroke
According to the 1939 edition of Pitman's book of the J.A.P., dry-sump lubrication became available in 1932 on standard motorcycle engines. So this engine was most likely built between 1932 and the Second World War.
