Winchester 38-55 box

Would love to know when this was made (window).

Shotmeister,
That 11-15 (Nov 1915) code on the lower right of front label provides you with an approximate, or ‘not earlier than’ date for your box. The top label probably has an 11-15 date also. Note that the red ‘W’ label on the end also is dated, it appears to be 5-14.
