Box of 45 ACP

Have a unopened box of 20 cartridges pistol ball caliber .45 M1911 ammunition lot F. A. 713. Can you tell the date of manufacture by lot code, I don’t want to open the box

I have a F.A. 520 that has “F A 33” in it.
I have a F.A. 724 that has “F A 34” in it.
I have a F.A. 764 that has “F A 33” in it.

These were all this way when I bought them, so I have no idea if the contents are original nor do I have any reason to believe otherwise.


That is a help. the box of 20 has never been opened and I did not want to be the first. thanks for the help
