Speaking of ammo boxes...
I found myself trying to make a deal on a nice un-opened box of Swiss Luger ammo at a gun show about 1 year ago.
I was willing to pay $ 100 for the box (which was Ordnance, dated 1924).
Seller insisted on $ 200 especially since the clear plastic "factory" shrink-wrapping was still 100% intact.
Of course such wrappings were not used...but he won the price-argument and I did not buy his box...
