I remember that when you could get a dog licence from the Post Office for 7/6d you could also get a gun licence from there for 10/-. This was for a shotgun. not a rifle; you still had to apply for a firearms certificate for a rifle. I had my first firearms certificate in 1966 for a .22 rifle for vermin destruction. I had about 30 acres of land cleared for the use of a .22 rifle; thing was, in those days, Mr.Plod didn't know the difference between .22 rimfire & .22 centre fire, or didn't care. (some of you may understand).
