My 1955 BCM Special with Dave Mills talking to Malcolm McLeod in the pits. Note the old cross plys and they were original cases with retreads of some soft compound rubber. The 1 3/4 carbs are off Ernie Sprague's Zephyr when he put side drafts on. Still in my ownership and still 2250 cc Vauxhall motor. Chris Read,Arrowtown.
