I happened to be at an estate sale discount center where the guy goes in and buys the entire estate for a set fee. EVERYTHING. Usually he goes in after they'v had a garage sale or another restate sale place tried selling a lot and a bunch of stuff is left over that they don't want. So he gets a real assortment of items.
Half empty containers of oil, cleaners, used tools, furniture, etc. I hit him up for his Avon aftershaves and his tools and supplies. Walked past this thing, knew it was plumbing related, and left it. Mulled about it and went back. Figure what the heck - if I don't use it for the handyman business I might use it at home. It was only after I got it home and cleaned and painted that I saw it was a Chicago Specialties. Now even if I don't use it it's part of my CS collection.
