The box was just a nice convenient place to store the removed parts: magazine cut-off levers, side-plate screws, original front and rear sights, pins and screws.
I have acquired Redfield boxes at a local hardware store and on ebay that had such parts. My best prize was a model 1902 carbine sight that resided in a Pacific sight box.
Sometimes, the boxes also contain old instructions and product information. I find it fun to reunite a commercial sight with original packaging.
At gun shows, check out those little sight boxes. There could be a 'pearl' within!
Attached is a photo of such a 'parts cache' that sold on ebay a couple of days ago. Also, shown is one of my best ebay purchases.
