I was thinking if you, or anyone else, is at all interested in the spindle chuck, I'd be happy to post the model numbers and other info off of it and even a couple pictures . It's a Jacobs chuck. I've seen them before in various shops I've worked in laying around different lathe machines, but never had the occasion to use one until now. They probably made them with different size threads for whatever spindle is on a given machine. Maybe it's a rare accessory you can find on the Fleabay or something. Let me know.
