I never heard of a trolley for a Sedburgh; maybe it happened after 1970? We (613 Halton) were used to trial the protoype Mk3 trolley (late '64) and it was constructed and repaired (when necessary) in the station workshops - you could get anything like that done at Halton in those days!
On the rare occasions when we transported a Sed on a Mk3 retrieve trolley (it was always referred to as a trolley not a trailer), we had one in the cockpit to balance it and one on a wingtip 'cos the cables were the wrong length. I can't think of the reason for doing it but we did do it very rarely.
