Showman William Wilson of Peckham, London purchased No.3938 new in 1922 and travelled with Rodes Switchback until the mid 1930s. It was then sold to amusement contractors Walls of Petersfield, Hants until being retired in 1955. By 1965 'Quo Vardis' was in a very sorry state and so Edward Hire of Shafesbury purchased the engine for restoration and is now an icon of the steam scene appearing at rallies all around the UK.
