Here's the patent dated June 12 1900 for the Nicol swivel that's listed on the box top Alan has. The patent is for a one piece design "ball bearing" swivel, maybe the one piece idea didn't work out so well.

I can see that there was probably more frequent rope failure with this design, and that you would have to take the whole swivel off the board to replace or at least tie a new knot. The two piece swivel we're familiar with is obviously the solution to this issue. Nice find, Paranday, btw.
