Oh, I agree, they do happen. I grew up in rural Somerset and remember quite a number of AEC Matadors operating as recovery vehicles, logging tugs etc. into the 1980s (by which time they were pretty decrepit), and several early post-war tractors in daily use. Some of the buses and coaches which took me to school were bordering on the classic even then too. Like I said, not unique but certainly worthy of recognition.
I'm not sure if it counts, but one local garage had a recovery hack which was a Rover P4 with all the rear glass removed and a crane built from old scaffold tubes protruding from the rear seat and boot area. Sort of Mad Max 2 with tweed .
