A chance to own a unique Bentley with great history and provenance which we believe holds a very significant place in the history of Bentley and Rolls-Royce Motors. Used as a test bed during WWII on official business, with every journey logged, it enabled the all new MKVI to be launched in 1946 when most manufacturers were re-hashing pre-war designs. The MKVI was closely followed by the Silver Wraith in 1947 and the Silver Dawn in 1949. We had previously thought that the B60 engine was a post war development but 3B50 was fitted with B60 engine No.4 originally, later replaced with No.11 as per logbook entry which is still in place to this day. We have copies of the three very comprehensive logbooks which not only record every journey but also who was driving and every modification carried out. These logbooks run from 1939 to 1950 during which time the car covered almost 200,000 miles before escaping the fate of most experimental cars by being ‘passed to Rm’ - the Chief Engineer who took the car for his personal transport. The car's life is well-documented, and included with it are copies of Ian Rimmer’s seminal work on the Experimental cars and ‘Silver Ghosts and Silver Dawn’ the fascinating autobiography of W. A. Robotham. Also various other interesting related articles, magazines and books. During our ownership 3B50 has had a brake overhaul, re-cored radiator and numerous other jobs. Now very sound, a bit scruffy, running well, very much on the road and MoT tested. Can be used as an ‘oily rag’ as is or improved cosmetically to the new owner’s taste. Chassis No. 3B50
