Looking at G-BAKT in Post #424, I believe this is the first time I've seen a 206 flying with the ground-handling wheel fitted. I remember that they had/have a spring-loaded retaining pin but nevertheless they came off the float pans easily after lowering the helicopter
Not an unusual sight in the 70's. A few operators flew like this. Usually into Battersea, which was half the size then as it is now, for handling and parking against the wall. Some operators modified the wheel attachments so they wouldn't come off without tools.
G-BAKU (location unknown)
The Location is without doubt Mann's hangar at Fairoaks. It's pre early April 1978 as G-AXGO went to the great hangar in the sky on the 14th of that month.
