I found this little Walworth pipe wrench in a grab bag at an estate sale. More than a handful of the 20 items in the bag worth the $5 each. I didn't even realize this was in the bag until I got home. Unfortunately, it is missing the adjustment nut. On the handle under the 6 is 43 and O. Does this mean it was made in October 1943?
Also, any ideas on where I might find a replacement for the nut? Doesn't necessarily have to be original.
