Great shape, smell terrible - USML PA120 40mm Ammo Can, Grade One

Not sure what previous life these lived, but by the very strong odor, it was for storing shrimp out in the sun. Had to immediately place them outside, and hose them down with dawn. Still attracting raccoons. I'll give them another wash tomorrow in an attempt to salvage any practical storage use. Surprised they didn't require a hasmat lable. No wonder they are final sale.
