I found these three no name dry guys at an antique store in my area that is going out of business. Drove by that shack a couple times a day for over twelve years. First time inside was today. I spotted these at eye level as soon as I walked in the door. I asked the lady how long she has had them, she told me her husband worked for public lighting in Detroit and they sat in the same spot for around fifteen years, since he died. They are clean as can be, may have never seen service.
