1959 Rolls-Royce Silver Cloud I Drop Head Coupe

Part-way through the production run of the Rolls-Royce Silver Cloud I, the company offered a drophead coupe by H.J. Mulliner, style number 7504. This new design, referred to as an adaption, was different from previous Mulliner Drophead Coupes and made use of a 'Standard Steel Saloon' body shell, which was heavily modified by Mulliner. In total, just 13 examples were built with 10 being left-hand-drive examples.

This post war custom coachwork car was created for Norman Paul Butler, a founder of Oak Brook, Illinois, who also established the Oak Brook Polo Club and developed the Butler National Golf Course.

Special features noted in the Rolls-Royce build sheets include:
- Special 'Ace' illuminated number plate box in place of Export with U.K. registration No. BC33 issued in 1903 on the boot.
- A 'Rev Counter' (the tachometer is mounted in the dash)
- Rear seat cushion is hinged to life up and form a luggage platform.
- Left hand drive - power assisted steering - electric windows and fog lights
- Power operated top and electric radio aerial.
- Micro switch on the handbrake mechanism controlling a warning light.
- Cold weather shield over door locks.
- Combined parking and blinking lights

The car was delivered to Mr. Butler in New York on May 15th of 1959 at a cost of $15,000. The car has been restored and has custom fitted luggage in the trunk and back seat.
