How do I take this tap handle off to access the ceramic valve?

[diywot]

Hi all, I'm trying to take this Fohen Furnas tap handle off to check the ceramic valve as there is a drip. I've taken it apart as so and then removed a small grub screw inside the screw hole. Gave it a wiggle, sprayed with WD40 and tried some degree of brute force but it doesn't seem to loosen up. Does anyone have any ideas how I should go about removing it? Thank you for any help!

Bumping to see if anyone has any thoughts on this. TIA

Check there isn't another grub screw down the hole.
It used to be common practice years ago to put a second one in a hole to prevent the first one working loose.

Thanks - the grub screw was a little one down the hole. I'm increasingly suspecting this needs brute force but I feel like I gave it a fair amount.
