Vehicle trace?

[Hedd_Jones]

I found reference to BF2. On a Gardner Serpollet Steam car new in Jan 1904 to the Honerable Humphrey N Sturt of 38 Portman Square, London.

Also BF5 another Gardner Serpollet, also Jan 1904 to the Rt Honerable Edward H Trafalgar (Lord Digby) of Minterne House.

Neither seems to have survived long enough to be re registered FX.

I found a Clarkson steam bus BF141/FX141, the highest renumber I found.
