Many thanks for your comments. They reminded me that WA was the Herald that took the Duke of Edinburgh down to South America in 62 on a big sales tour, and I think WC was earmarked as back-up. I worked on them both at Woodley in preparation for the tour and well remember the luxurious fittings we had to fit to WA and how smart the old bus looked on departure. We hoped then that HP would get a contract for a military Herald, but despite very good results at the Martlesham Heath trials against the 748 politics decreed that the contract went to Avro and civil sales did not 'take-off', as it were.
