The ship name is COPRA. The physical location of COPRA was at Largs in Scotland but only a small staff actually operated there, they held and managed the pay and victualling accounts for small vessels, including all landing craft, worldwide. Sadly there is no notation to indicate which landing craft your father served on so, unless you have some other way to pinpoint which landing craft we may never know,
Looking at the Service Certificate we have:
ROYAL ARTHUR – new entry and basic training establishment at Skegness.
CABOT - Training Establishment in Bristol (possibly Stocker/mechanic training).
DRAKE – RN Barracks, Plymouth - awaiting draft.
QUEBEC – Training Establishment at Inveraray.
COPRA – Accounting Base for small vessels including Landing Craft.
DRAKE – RN Barracks, Plymouth. Awaiting Discharge.
