Chassis LSMH57 is a 1959 Rolls-Royce Silver Cloud I Drophead Coupe Adaptation by H.J. Mulliner — one of only 13 built and among just 10 in left-hand drive. Commissioned by Norman Paul Butler, co-founder of Oak Brook, Illinois, with an extensive and costly list of bespoke features, the car was later treated to an exacting body-off restoration by noted coachbuilder Mark Schlachter of Metalkraft Coachwerkes and has since earned multiple concours honours.
