37304 passes Horsemoor on 16 August 1988 with the 6E16 13:40 Duxford to Tees Speedlink. Most pictures I have seen of this working give the headcode as 6N84, but the May 1988 East Anglia working timetable definitely has it as 6E16. The four tank wagons contain glue from Ciba-Geigy's factory at Duxford.
