Most of the rockers on old bikes would have the 5 inch sheaf knife with the leather ringed handle and alloy ball top. What we bought were the large Bowie knives. Awesome looking weapon. What we did was go out in the area locally where there were 6 foot high fennel plants and chop our way through. just had fun with them. Most air guns were .177 so just sting a bit if you got shot. This bloke who now has the false leg bought a .22 target gun with quite a long barrel. That one really stung so we avoided shooting each other with that one.
The firework battles in the local common MOD buildings were good with each having 20 bangers in pitch black. How we survived is a mystery. Climbing under the old wooden pier, throwing each other into the docks, running train axled timber carriers down the rail lines, hollowing out timber stacks for a camp and jumping off the giant sand hoppers that were sifting sand. We just jumped from the top into the sand heap. All until we found motorcycles and we then became safe !
We scrambled an old BSA 600 sidevalve around a quarry until the clutch went so dumped it in the quarry. Then a Sunbeam S7 found burnt on the beach and managed to get it running around the docks until we dumped that one. This mate, in 1973 bought a brand new BSA B50 which was nice but later went to riding older Velocettes. The Velo he had his accident on is still in use now.
