Inquiring Minds of WWII Shotgun Shells

[Rescue190]

I picked up two packages claiming to be WWII OO Buck shotgun shells. Void of any markings and packaging has been similar for a long period; I had to open one of the two boxes. Now I had to share so inquiring minds will already know what is inside. I was hoping for brass shells in lieu of paper shells but happy either way. I can sleep now knowing. Very little verifiable info available that I could find when researching.

Nice impressive ammo box in any case Rescue. Box kinda predates my age group but I would guess 40s or a bit later. Love how the box says smokeless loads.
