Can anyone help me to identify this carbon boom?

I got the boom for free and am now looking for a suitable end piece which is broken.
The grip has been renewed and the previous owner no longer remembers the brand and type.

The length of the boom is from 160 cm. and extendable to 210 cm. (=60cm).
The adjustment clips are double pins and are 2 cm apart.
The diameter of the grip is 30 mm.
The diameter of the adjustable tailpiece is 22mm.
The boom end has a 'loop and go' system.

Probably about more than 10 years old.

It gives me a Unifiber feeling but I'm not sure.

My questions:
1. Which brand, type and year?
2. someone else with an end piece with 22 mm. diameter left?
3. does anyone have experience to repair this (broken part is missing)?
4. other ideas to make the boom usable again?

1998 POS Carbon Fat 160-210

Looks a lot like my Windsurfing Hawaii carbon boom, head clamp is identical, tail piece is also identical except for the rivet position. And it looks a lot older than 10 years. My older Windsurfing Hawaii boom uses the two pin locking clips, and those clips also fit my much newer Epic carbon boom.

as for the tail, replacing is really the only option, have seen Chinook tail ends for sale on the web at major online stores, call and get specs like hole diameter and spacing, and tail tube diameter.

Looks like an Autima boom to me.
Surf Sail Australia [in Perth] has parts.

And fat POS is a bit harsh, they're not as comfy for grip but they are stiffer.

I'm beginning to think the boom is a 'Techno Limits'.
This is my boom head:


And this is a Techno Limits boom head I found on the internets:


So now I'm looking for an old Techno Limits carbon adjustable boom end.
The diameter of the boom end is 22mm.
The grip diameter is 30mm with foam and 29mm (?) without foam.
Pin holes 20mm.

One leg of the adjustable 'rear/tail end' is broken of and missing. So it isn't fixable.
You can see it clearly in the first topic-post on the first photo.
It's useable range is now 10cm.
