A family friend gave me that exact set in the early 80's to work on my bicycle with. I finally got a tool chest and found a bunch of the sockets that were mixed in, they all look like they're cast aluminum, :lol_hitti
It's amazing to read the same story over and over that mimic's my own, searched high and low reading, scrutinizing, checking out different brands and models in stores to decide that the HF box was the best choice for the price. I bought the 44" box a week ago, it was on sale for "$399" however...
