As a kid I lived in Bexley and one of my 'playgrounds' was the butts for what I think was the Vickers works at nearby Crayford. I dug many interested 'bits' out of the sand including 20mm Hispano and a 25.4mm Vickers! One piece that I still have is pictured next to a 'standard' 0.55" Boyes head; it used to have a steel core (long since lost) and I wonder if anyone has info on this 'long' version of the 0.55" Boyes?
By the way, my playground was cleared when the A2 was widened many years ago!
