First, I want to take an opportunity to thank the Mods for accepting me on the forum. I've recently purchased a new to me 14" x 40" Challenger lathe from a widow. It came with a wide array of tooling, measuring tools, etc. The change gears were in a small tool box which included this item. I have no idea what it is. Can anyone shed some light on this for me? Thanks.
