No, not that kind of dating although I feel I should be married to them by now!!!

I am compiling a data sheet of all Winchester Western 44-40 ammo boxes from 1928 to now at the below link. The only way I can finish this list is to get help from the 44-40 community. The ink stamp code is on the inside of one of the flaps.
The data can be seen here: https://docs.google.com/spreadsheet...lv6tCWBJsCOB8vLIDOIg/edit#gid=1860800684
