Any Bicycle Guys Here Can Tell Me What Headset This Is To Replace?

[SquirrelMadness]

Bought a bike off some FB guy for 20 quid but a lot has been changed on it.

Getting it ready for summer bike rides but needs a new headset as it appears to be incomplete.

Here are the pictures of old headset:








Obviously there is something dodgy going on as that bearing race at the bottom shouldn't be exposed!

Any help would be appreciated as I dunno what to buy. Also would that old headset need to be knocked out from inside the tube when replaced?

Cheers guys.

OK I knocked the old cups out and got this:




So that linked headset should be same looking as this? I know some headsets have massive cups but these are small.

Also are those bearings integrated to the cups? I can't seem to separate them.

And don't these headsets come with fork crown race or do those have to be bought separately? If separately how do I know they are compatible with the linked headset?

I will be changing the forks too.

Thanks.
