I picked this up from a cheapy bookshop in Buxton for £5.99. Turns out it's cheaper on amazon...
Anyway, it's worth watching- a couple of smallframes at the factory (he doesn't mention the 90ss) and some PKs in attendance when they have a ride around the town at the end. Mostly '50s & '60s large frames, though.
Worth having in your collection, especially if you get it s/h for 66p + P&P!
I went to a night club but it was too dark to see the seals.
