Like my reply on the Britannia, I also never had the opportunity to fly on the Herald. My memories of Heralds are also from Dublin (from the early 70's through to the early 80's). At that time, they were the mainstay of British Island Airways (BIA) and before that British United Island Airways. The BUA colour scheme I remember them using was the biscuit and pale blue scheme with black BUIA lettering on the tail fin. When BUA was absorbed into the "new" airline, British Caledonian, BUIA was sold off and became BIA. Their new scheme consisted of a mainly white fuselage with a broad red cheatline and a red tailfin with BIA in white lettering on the fin. BIA flew from Dublin to Blackpool and the Isle of Man and the Heralds were regular sights, almost daily, in fact. Not many Heralds were built so other operators were rare. British Midland operated a few and occasionally one would replace the usual Viscount. Even rarer were sightings of European Air Services Heralds. EAS was a French airline and flew student charters in the summer. They normally flew Vanguards (ex-Air Canada) but ometimes replaced them with one of their Heralds. The Herald was an ecomomic disaster for Handley Page, its rival, the Fokker F-27 Friendship, was such a superior aircraft that the Herald never stood a chance in the market place. Only about 40 were built.
A friend of mine flew to the Isle of Man on a Herlad in 1974. What fascinated him was watching the mainwheels retracting into the engine nacelles after lift-off, n particular, the pilot stopping the rotating wheel by applying the brakes just before the undercarriage was fully retracted. He also said it was quite noisy and that he was glad the flight from Dublin to Ronaldsway was a short one.
