You guys are a bad influence. After reading the op, I looked in my stash and came up with one, no tray, rusty, needing dents in front removed. Found it years ago at a dumpster. I have given thought to putting my set of double line v sockets and ratchets in a Craftsman box, maybe giving it to daughter and SIL. Looked in one pawn shop today, found a box with tray like the first one shown by op, top and sides were at the stage where you ask do I refinish or wax to preserve, bottom very rusty on outside. Marked in magic marker(a turn off) $12. Guy wouldn't go lower that $10, so I passed. Got one at another pawn shop, with tray, rust all over but no deep pits, $1.00.
What color is that metallic gray Craftsman uses? Some official name or paint number?
