Here's mine in serious need of cleaning.
I bought the one on the right 20 years ago and it was old then
I paid a $1000. for it and remember telling the guy that's a lot of money for an empty tool box. He said look inside. It was full of Snap-on, Mac, etc tools. I was happy, he even let me make payments. The one on the left was bought one piece at a time. I got the top box from a swap meet for $250.00 and the bottom in pieces and badly faded, but it was free. I had it assembled and cleaned in three hours.
The friend who gave it to me couldn't believe it was the same box. I repaid his generosity by fixing his truck. I'm trying to find a center section for the larger box. My son is quite the smart guy, he sometimes buys me tools and I said that was nice of you. His reply was their going to mine some day anyways.
