Hello, I took some tools down to Martin Donnelly's last week with my brother-in-law. We stopped at the Glenn Curtiss Museum on the way home, great place to visit, THANKS Amecks!!! We stopped at a garage sale in Penn Yan and I found this set of 1/2" drive Mustang Sockets, they cleaned up well ( before & after photos ). From what I have read, these were an economy line from New Britain? They seem to be well made, crisp stamps, knurled band. Regards, Lou
