Hobbit,
G-BDOG is indeed alive and well and living at Netherthorpe airfield.
The undercarriage is still retractable, though the current owner did some years ago replace it with a new retraction mechanism. In addition the canopy has been re-designed with gull wing style doors and the rear seats have been removed.
I was lucky enough some years ago to fly in the aeroplane and thoroughly enjoyed the experience!
p.s. the current owner insists that it is a retractable BullDOG, not a Bullfinch....
