I just scored mine last month. It was in Tennessee and I drove out to pick it up.
I first saw one in the office of a parts warehouse. It was all restored and looking sooo good.
then I saw a picture of one and knew just what it was and from that day forward I've been on the hunt for a Snap-on K60 tool box.
I stumbled onto an old facebook post that was 6 months old and it said there was one available if someone wanted one.
I quickly sent a message to the fellow. He returned a message saying that it wasn't his, that he was contacted by the owner 6 months ago trying to sell it to him. I asked him if he still had that contact and he did. He sent me the info and I followed it up. The gentleman in Tennessee said he had forgotten all about the toolbox. It was his Dad's and yes I might be able to acquire it, if I was planning to give it a good home.
I sent him a shot of the Big party garage and he said it's yours. I drove 5'500 miles round trip in 6 days to pick up the tool box and an Alemite wall in Chicago Which was another holly grail piece for me
MY snap-on treasure
