Z-Vice Turntable

I have purchased a second hand Z-Vice (they don't seem to make these anymore), and it did not come with several of the accessories.

This is a turntable (plus additional washer) for the Z-Vice. It should enable a few degrees more movement than the original Z-vice turn table, although it won't be as strong as an original alloy one.

Below is a YouTube link to the Z-vice so you get an idea what I'm on about (hope I'm allowed to post links here).
