Port-O-Jam

Jamaica and UK label. The original Jamaican imprint, owned by Clement “Coxsone” Dodd, was used primarily for mento and calypso releases. The UK imprint was a subsidiary of R & B Discs Ltd. It seems to have been an overspill label for Dodd’s productions, but changed halfway through its run to become an outlet for Ossie Irving's UK productions.
