Thank you for the point. According to Bonhams in 2013:
"1934 Lagonda Rapier Supercharged Single-Seater
Chassis no. D10840
Engine no. D155
Footnotes
Originally registered 'AYM 787', this Lagonda Rapier started life as a fixed-head coupé bodied by Abbott of Farnham, this being the most popular body style fitted to the model in 1934. The car was delivered to Lagonda's main agent in London, Warwick Wright, on 7th June 1934 and is believed to have been registered on the same day. London registration records did not survive the Blitz and Warwick Wright's sales records no longer exist, so there is no information about the Rapier's owners or history pre-WW2. This car is listed on page 18 of the 2011 Register of Lagonda Rapier Members and Cars."
