Batchy,
I think 1983 would have been the last year that Rothmans sponsered the Pitts. By that time they were concentrating on the Pitts solo display flown by David Perrin in G-SOLO.
G-BADW was bought by the Aerospace Museum at Cosford in 1980 and statically displayed there with the Rothmans Stampe G-AWIW. A change of musuem policy meant that the aircraft were put up for sale in 1984.
Once sold, G-BADW was then brought up to airwothiness and flown for a couple of seasons from 1986 in Rothmans colours before the arrival of a sponsor dictated a repaint.
