Very good profile, little similarity with KAI MARU (Fairfield pic).
IMPERIAL was built by (Ishikawashima Harima Ja) in 1965 as IMPERIAL II,
with 3 sisters ACONCAGUA II- MAIPO II- COPIAPO II.
IMPERIAL was broken up as the Greek ALLIANCE SUCCES in 1981.
The same lot had the sisters that were scrapped 1980-81.
I hope is good for you.
