The female element of a two-piece copper-alloy swivel for suspension or strap distribution. It is shaped like a finger-ring with a plain hoop and a sub-circular 'bezel' with opposing oblique grooves on either side. The 'bezel' has a radial hole through its centre, which would have accommodated the integral rivet on a similarly shaped male element. The complete swivel would have looked something like UKDFD 44681.
Suggested uses for swivels of this type include harness applications, dog leashes, and for linking the leash and jesses in hawking. Close dating is difficult.
