“Twenty” was a smaller brother of Silver Ghost. The car featured 3.127 cc OHV inline six-cylinder engine and made its introduction and was officially announced in October 1922.

This special "Twenty" has spent most of its life in New Zealand, but was purchased new in London by Mr. George Humphreys, who was on holiday in United Kingdom. The coachwork is built by renowned coach builder Windovers, whose brass plates are mounted below all four doors of the body. The car features split opening windscreen, town and country horns and original 1920’s batteries for intercom still in the battery box under the driver’s seat. Linen domed covers for the cloth seats were specified when the car was ordered new and still remain today. This automobile is in beautiful preserved condition and at this moment needs some recommissioning.

Rolls-Royce 20HP was very popular car in the day, intended to provide a smaller car for owner drivers as an alternative to the Silver Ghost which was in production at the time.
