Turks head?? What knot is this

[Bigdog]

I’m trying to repair a older vintage blackjack I have. I have learned the braiding 8, 12 plait but the head is giving me trouble. Here’s a picture of what I need to learn to do. Is it a braid or a extended Turks head??

Here’s a second knot I need info on. Thanks for any help

Both. A Turk's Head is a kind of braid, just closed at the end into a stopper.
To see what I mean, make one, but don't tighten it down. There's a gap in the crown, so put a dowel through that and tighten it onto that. Now slide the dowel down into the TH just a little and start to tighten it again.. The next trick is to rework it, keeping the weaving going for two more entire circles. Finally, generalise it so it can be done for a goodly distance.

A useful tool can be to put tacks into the dowel (a broom handle must commonly) so you can weave without things untwisting.

In the picture, the handle's covered first, then the knob.
