I was looking up some Snap On tools I inherited and I found no search results at all for this tool number. It is a deep offset 6 point box wrench, 5/16 and 3/8 ends. See attached pictures. There is a patent number on it which is from the 60s, so it it's not crazy old. Any ideas why there are no search results for this? Is it a rare one or got its number changed? Maybe even a fake? Curious.
