The brown suspension disks were two JD 's dated 5/1949, A Locke, dated 1942 and an Ohio Brass dated 1945 with the sandblasted mark. Yes, they are pretty ordinary but mean something to me because of the previous utility they once belonged to. The sky-blue yuk suspensions cleaned up an look like new but they are Chance brand, dated 1980. Common around here and I was surprised how lightweight they are, all the metal is aluminum. The 2 pintype "bowls" are a Locke U-757 and an O-B U-758 and were also contaminated.
