I’d say look at the manufacturing base in your area, like the shops that would give you heavy vises. Also when the area was settled. With the Northeast being settled before Las Vegas, I expect older settled regions to have better access to older tools. And since Vegas was never a manufacturing center, they have a double whammy of no good old tools or machines.
Things near here are OK, with all the manufacturing of ships, and parts for those shipsBeing close to a major airport, especially one that used to be a major maintenance site as well..
I also feel that being near farmland is a mixed bag, where there are lots of tools, but they are used HARD, and often in horrible shape after a few years. Being on the edge of both the airplane mechanic’s homes, or retirement homes, and farmland galore, we have some tools available.
oh, and all that salt water around me is harder on tools than high humidity. Imagine farmers tools with rather added bonus of extra rust.
I used to think we were a desert wasteland of tools for about my first 8 years of looking. Then I met a few guys that had metric boatloads of vintage tools, and realized I wasn’t looking correctly. Wasn’t starting early, CL didn’t exist, didn’t know of auctions, didn’t know what an estate sale was. Turns out one of the guys with the tools would get to an estate sale early, and buy the ENTIRE garage contents.
I found the harder I looked, the luckier I got. I bought two wooden carpenters chest full of tools, and got a Stanley #1 plane included. All my buddies were jealous, but several admitted I was working harder, making slightly risky moves to score tools.
