I remembered this post with the reply from RHARROLD, the great, great granddaughter of Albert Harrold and finally got all 3 of my Harrolds tools in one place. I contacted her and asked if she would want them. So, they are in the mail today.
Here's a link to photos:
The adjustable was dug up from the dirt under the back porch of the 100 year old house where I used to live. Most of the "stuff" I found there dated from the Fifties. I mentioned that I soaked the adjustable in vinegar for about a week to clean the rust off. It worked well. I had a tray of vinegar and covered it with a piece of white cardboard so it wouldn't smell up the shop. When I took the cardboard off there was a brown image of the wrench on the white cardboard, probably caused by bubbles popping on the surface of the vinegar. One of the Tool Talk guys called it "The Shroud Of Harrolds" or something like that, referring to The Shroud of Turin.
The smaller pliers were in a box of old rusty tools given to me by a neighbor. The larger pliers were in a tool box I purchased for $5 from a company that does "cleanouts".
