Better too much good advice and options than too little!
The L shaped piece of metal was to prevent handle damage, not hold the head on. Lots of people miss their mark and end up chewing up or cracking the handle just behind the head. The metal strip really helps preserve the handle in that case. These days, we'd tend to wrap a strip of fiberglass around as a quicker but uglier method.
It was good to hear about drilling a hole in the back of the handle and filling with linseed/turps, then plugging. I thought that that was a trick lost in time. The old timers would use regular linseed oil, not the boiled kind that dries. Some liked to use kerosene (parrafin over in UK) and I wondered about that until I found that people who shoot muzzle loading rifles soak their wooden ramrods in kerosene to make them incredibly flexible. On big axes or mauls, having a flexible handle cuts down on the shock coming back to the wrists.
