The new owned of the 1934

The new owned of the 1934 Frazer Nash BMK 104, originally owned by Alan Whiddington, wants to trace the history of the car from when Whiddington used it in competition, to its acquisition by the first post-war owner, believed to be John R F Pilston, and who was the owner after Whiddington disposed of it, probably around 1937/38. Can anyone fill in?
