Sorry about the confusion over image size.
The first shows the Physics lab. From left to right are John Nurden, Glen Rogers, with Robin George doing his best "Clonk" Clenaghan impression.
Second was taken at the old Sheerness swimming pool, with the older school building in the background.
Third was taken in room 5 I think, again sorry for the quality, it also suffered light fogging. Pictured are Phil Goodwin, unknown, Ivan Hurket, Terry Pack, Colin Brooks, unknown, and Filmer Wellard.
And finally, the gym, and the world famous "below knee football". Left to right, Filmer Wellard, Ralph Leach?, Barry Spokes, Peter Glock, John Nurden, Terry Spice.
I'll keep digging to see if there are any more, if you're interested.
