Dug Cans

These don't include the numerous Beer/Sodie-pop cans I dig, nor anything I've dug since the summer.

We have a Mobiloil Outboard can, which was face-down beneath the surface when my shovel struck it something fierce (Grrr, at least it was the back.)
We have an American Oil ___Lube (rusty!) that I cannot even recall where I dug it at anymore as it's been so long (I really wanna see this one clean!)
We have a free sample of Firewax Fire Starter from 1962ish.
We also have Klear Floor Wax.
And we have Strictly Pure Orange Shellac from the 1940s.

I dug 'em all, and, yes, I also brought the junk home. :P

Ideas on age of the others? I'm still learning how to safely remove rust.
