I am wondering if they did have real firearms or even shotguns which can be carried on private land with permission of the landowner.
I don't know much about rifles or what type they were but they were certainly not toys. It does appear that the farmer who owned the land that later became Hawkesley had given this group consent to build their gathering place on his property, unless of course it was without his knowledge. The thing is that they were carrying their rifles in the neighborhood rather than just on the farmland. At times there was an armed sentry at the bottom of Green Acres Road on the corner of Redditch Road. One thing that I neglected to mention was that there were some women in this group as well.
There has been, in America at least many survivalists, vigilante. Military style religious groups who wish to save the world for the greater good and themselves.
Living in California now, I know this too well...
I really wonder if this was going on in other parts of England in the early sixties or if it was just an isolated case of crazy.
