From Stuart Ulph:
the GE in the photo is of particular interest to me because the driver (who seems to be yodelling) is said by TLC to be "B L Byron" but I think it is B L (Lewis) Byrom. If I am right then NE 552 is most probably the Brooklands that the Byroms transmogrified into their Southport racer which, in turn, became Pete Almack's special. Of course, Lewis might have had more than one Brooklands but I rather doubt it. As far as I can determine, records for this reg. number are lost. Kevin Desmond, in his biography of Dick Shuttleworth, quotes an unlikely reg. no. for the car (SFY 166 from memory) and I have failed to find any details about that one as well. He also says other things which make me suspect his proof reading.
