Hi Iain
The craft was built in 1965 IIRC and was originally a peripheral jet craft but later fitted with a skirt. It seated around 60 passengers and was powered by a 2500shp gas turbine. It also had sprung wheels to aid it over rough ground during it's peripheral configuration. I have some detailed spec's I can dig out & send if you're interested. It was certainly a craft that caught my eye in my early years - it has particularly pleasing lines.
