$200 4-Jaw Independent Chuck Part 1

This is a $200 4-Jaw, D1-3 mounting, 8-Inch Lathe chuck from China. My 1970 manufactured South Bend lathe came equipped with a Cushman 4-Jaw chuck but many classes of shop students left it with inoperable operating screws. I purchased this using Ebay from this seller: https://www.ebay.com/itm/D1-4-Direct-... After I received the wrong item, I reordered and received this chuck.
