Just been and visited the oracle (my dad) The travel agent models were made by the model building department of Zambia engineering in Ashford, Kent (they traded under the name Tech-pro) the models of Hengist and Horsa cost £200 new, the St Christopher models were bigger and cost £600. they were made from moulded plastic. the bigger builders models were more expensive at £2000 each and the half hull models (20 + foot long) were over £6000 each.
My dad has original oil paintings of one of the ships plus 4 of the limited run of 150 prints from the painting, on the painting you can see where the livery was changed before the prints were made and the oil painting was modified to reflect these changes.
my dads title at sealink was ports manager, he used to run around as a general dogsbody for the managers and directors, one of the builders models at over 6 foot was taken home by one of the managers and his son renovated it for them.
