Almost certainly this Fox Moth. https://www.airport-data.com/aircraft/G-ACEJ.htmlAbout 1952 aged 9, de Havilland Puss Moth from the beach at Southport Beach. I don't remember sight seeing, just the vision panel looking straight down.
I grew up in Southport, the comments about a 7/6d flight were obviously after my schooldays, I couldn't afford the then 5/- flight around Blackpool Tower with my 6d a week pocket money ! The reference to the pilot Gyro, was a Frenchman called Gyroux, and in later years I was involved with a flying club which shared a hangar with him at the Northern end of the town. He would drive up, pull the aircraft out of the hangar on to the beach, open the cabin door and his dog would jump in, then he'd fly off to the beach near the pier, where he collected his passengers. Cars were allowed to drive on the beach at that point too, tho' I don't recall any near misses ! The H & S lot would have a fit these days !
