The rifles are still out there.
I live a long way from any true "gun stores", and my visits to such stores are only happening maybe a couple of times per year....BUT:
Not that long ago, a friend took me to a newish store in Reno NV which I had not previously visited.
On the "used" rack were TWO #4 Mk1 rifles. One was a British version in about NRA Very-Good-plus condition, asking $250 and worth it, in my opinion.
The OTHER was a real gem, being a 1943 Long Branch in NEW, UN-ISSUED condition, for an asking price of $350. I'd been looking for a good long Branch 34 for many years, and here it was. After a little dealing, I walked out with it for a total of $315, taxes and phone calls all paid.
One just never knows...
Can we say, "happy Camper"???
