Years ago, when the old hardware store closed in my home town, all the old inventory came out, including stuff probably in stock due to the long-ago disappearance of the manufacturers. There was big governor from a steam tractor, I had to ask the old dad what it was.
My step father had a large chest of old hand tools. He told me they had been the tools his dad had used when working in the old cotton mill. Odd looking wrenches big as a baseball bat.
When the mill closed down he took them home with him as they were useless anywhere else since there wasn’t another cotton mill in the state. It was real interesting looking at those tools. My step father knew what each of the tools was for since he had worked at the mill himself.
