old tool boxes

as many of you know already, i have a love for craftsman tools...especially the older stuff.

well i found these old tool boxes that my dad thinks are from the 70s .....i found two at a flea market for five dollars each and the third one on a trash pile by the street that was going to be picked up by the trash collectors.

i want to restore these and use them to replace the plastic cases that come with the new tool sets now.

so any hints or tips on how i can restore these ....i think the color is silver hammertone ....not sure. all three are complete with the tray that goes inside.

i think they are really cool and i would be very happy to make them nice again and get rid of the plastic cases i have and have some older craftsman items.
