I got this far…
i think the number inside is k937a01
But Google didn’t offer much help.
There’s no other screws, bolts or pieces of gum holding it on that I can find.
I’ve tried pulling on it, tapping it with a hammer and asking it nicely.
But this thing just won’t come off.
No brand on the tap, quarter turn kitchen tap mixer
Any help would be appreciated!
Edit: some oil and something prying under it did the trick
