A friend of mine's father has been diagnosed with mesothelioma, and his family is trying to trace his employment history dating back to the early 1940s (his father is experiencing the onset of dementia and can't remember a lot of things).
Part of his employment was working at a machine shop on Pacific Ave. in 1942. Would anyone have any suggestions as to finding the names of machine shops in that area at that time?
Any help that anyone can give would be greatly appreciated. I'm at a loss as to where to look for this information, and my friend isn't very web-savvy and has asked me to help. Thanks in advance.
