Last known owner seems to be a gentleman in the Cardiff area.
The G-INFO listing is a bit of a muddle - five separate owners appear, two of whom are deceased, one of whom is Bertram Arden, well known for a treasure-filled barn at Heavitree, Exeter in the 60s/70s.
I remember my father remarking about the barn as we drove through Exeter on the A30 around 1971.
Presume the old dear still exists and is perhaps enjoying some restorative care.
That's a lovely looking aeroplane you have there 369 - is it still that lovely shade of yellow?
