Anyone else keep an eye open for old tools? I picked up an OLD circular saw for $20

We watch for old USA made products. Old Pyrex, that was made in America.
Some of the new Chinese Pyrex has a non-homgenius blend of components (Borosilicate glass) that tends to shatter in the microwave. Given to us were old floor fans by Westinghouse and GE. These things run forever, and will be passed down to other generations. I have many old machinist tools (Brown and Sharpe, Millers Falls, etc) that are 70+ years old and still function perfectly.
We desperately need to get manufacturing BACK into this country. We are quickly becoming a service nation.
