"Although Bentley ch. no. 708 may no longer be in existence, I have the Axle nose piece which was obtained from T.P. Breen Ltd. car breakers in the early 1960s which presumably may have been fitted to the car as original equipment. See these photos where the ch. and ratio 708 15/53 can be seen stamped on the top flange. The ch. no. 686 and ratio 13/55 can be seen in bold digits on the main casting presumably the axle piece was originally destined for 686 and was changed by Bentleys as both chassis were produced at about the same time in 1924."
