Plenty of nice memories from this Peter Fleming video of the Brinks as a time card mud fest in glorious weather. Oh those less Health and Safety conscious days. When you have some time take a look https://public.fotki.com/MACC-MAN17-CNWTRIALS/enduro/pre-1990-brinks-enduro/.
There are loads of pictures as well from both Trials and Enduro's.
Enjoy free from Manchester 17.
