Onan More likely at your age they were Handley Page Heralds which used to do the IOM route then.
Being born in Southport,Woodvale was also my 'first sightings' in the '50's.Seem to think there were Javelins based there.Couple that to both Mum's sisters were telephonists at A.V. Roe where I got invited to the Christmas parties.Shackletons being built in the hangar at Woodford and Father Christmas arriving in an Avro Anson.Oh and me Uncle Joe who flew in the RAF.
