This new prototype becomes the first unit of the most prestigious model of the brand, the Brough Superior SS100 Alpine Grand Sport (AGS). It has been discussed previously in this column (unsold at Phillips de Pury in December 2010).
Commercial production is announced in September 1925. Compared to the basic SS100, its center of gravity is lowered and the tank volume is increased. The engine is a JAP Special designed at the request of George Brough.
The eighth AGS is purchased by T.E. Lawrence better known as Lawrence of Arabia. This is his fifth Brough. The thirteenth AGS, delivered to its first customer in November 1925, is estimated $ 350K for sale by Mecum in Las Vegas on January 25, lot F123. The twentieth, delivered to an agent in January 1926, was sold for £ 280K including premium by RM Auctions on October 31, 2012.
