Not one, but several!
Alpha Fox at Filton for certain (I've seen it), Alpha Charlie at Birmingham almost certain, Alpha Golf at Seattle (was pulled out by a vandal, but they slid it back). Not sure about Alpha Delta in New York or Alpha Echo in Barbados.
IIRC, at Mach 2 there was a good two inches between the right side of the flight engineer's panel and the bulkhead, and less than hafl an inch on the ground.
