Vintage Lathe Machinist Metal Lathe Tooling South Bend Lathe Atlas Lathe ?????

Description

This was in my grandfathers shop. NO CLUE WHAT THEY EVEN ARE. They were in one of the many lathe parts boxes. No manufacturer's name on them that we could find. If someone can point us in the right direction to what they are so we can list them correctly. That would be great. Please judge this auction by the photos. Thought someone would like to have it. Sold as is. All sales are final. Shipping to the lower 48 states only. We will not ship out of the 48 states. Thank you for look
