Remington 30-06 MATCH box

I am discussing some early 20-ties match box from Remington with a friend and while comparing the boxes, I noted a code on one of the labels. One box is marked 137-P while the others are marked 122-F
See Pictures below.
The boxes with the Code 122-F have a code stamped on the Bottom. One is stamped DH024 and another is stamped Y03N.
The box with the 137-P Code is stamped on all sides with FEB 1922

Anybody any ideas ??
Thanks

The actual date being stamped on all sides sounds like it was done by a person, not the factory or an arsenal before being issued.

Can’t help with the code.

Thanks for your reply Pete. This is what it looks like (on front, top and sides of box)
