Some time ago I was into collecting and somewhat still am, Belgium Browning A5's. I searched the internet and had built contacts all over the country to find vintage A5 boxes. I found them in all kinds of condition. I accumilated several pristine boxes and have one empty one now. We ( my buds )copied labels and made them out to match our guns. I even had Browning Auto 22 and Superposed boxes. My buddies found someone who had a stash of original labels and they bought all of them. I still have some.
At that time I was also into Winchester 42's as well. What I did see is the 42 boxes were a lot higher and harder to find than the A5 boxes.
Oh, I paid anywhere from $50 to over $200 for the A5 boxes. I even found original manuals. It makes a heck of a display to have a as new A5 sitting in a nice box with a nice manual to match.
