I got these two PLUMB box ends from A hardware store in Honoka’a Hawaii Island, where we lived for years. Ikeuchi’s Hardware. I was friends with the family since the seventies. They “closed” the store but still sell off old stock they’ve pulled out of the attic. There were boxes of these new wrenches, from the 1940’s maybe. 100 year old store that sold everything, at one time. As an example the old man back in the day made galvanized buckets and wash tubs out of sheet metal. on a metal bending , rolling set-up. They couldn’t easily order much merchandise back in those times. So the locals had a lot of business. Third generation now. My favorite tools have old connections to friends and family. Haven’t used these but a little yet. But the sizes work on a stovebolt!
