An empty 2pc half-split box which originally held 10 shot cartridges.To quote from the book One Hundred Years of Winchester Cartridge Boxes(thank you Ray & Dan)"this is the only caliber,rimfire or centerfire,to have been offered in a 10 round two-piece,standup box with dividers"(the dividers are present).One edge of the top has a separation and I will shrink wrap it making it virtually unnoticeable.The date on the front label is "3-11".
