Here's my stab at what's relevant for 1982. As the pictures in general seems to be from Oulton Park, it sets the date on April 4th 1982, as it was the only round of the BSCC held at Oulton in 1982. The entries were split in two seperate races - one for class A and B and another for C and D.

Vince Woodman, but can't tell which year. The number and positions of Dunlop stickers might tell those better in the know.

This picture seems to be too bright compared to the others, so might be from 1981, but can't tell!?
