Hello, I stopped by one of our local Industrial Supply Houses today to look for an older Mayhew Catalog. They asked me if I wanted to look through the old catalog room. I said no, I'm kind of busy right now. Just kidding, of course I took a look. Nothing very old, hundreds of catalogs from the 70's and 80's. I was told that I could only take what there were duplicates of, or a line they no longer carried. They have a list on the wall from A to Z, most were common, some obscure. I will be going back. Pics are a sample of what I found. A good day!!!!!! Regards, Lou
