Headset Tool C Spanner Wrench Bicycle Billings Dualcast Tools Vintage Lot of 10

  
I believe that most of these are old bicycle tools. You can tell from my pictures that they all have been used and are rusty! Top three tools show what appears to be the brand Dualcast. The next 6 in line, I cannot see a makers mark on, but some may have them under the rust. The wrench off to the left in my first picture is marked BILLINGS. The wheel spins on the wrench, but it does not move the head of the wrench at all. The head seems frozen into the body of the wrench. Not sure if it would come out if someone was to soak in some kind of lubricant. Please enlarge all my pictures for a better look. You should have this item in just a few days after it is mailed.
