    There may have been four screws at 90 degree points around the loose part. Look for tapped holes, or maybe the screws are still there, but backed out. The screws could adjust and lock in position a...

    I think the rare spiral geared chucks have an S on the model, like 16S. The 16N chucks made in the USA are fairly common on eBay and old used K4 keys are probably not rare.
