Removing b-post finisher on XJSC

Hi
I’m working on re-painting my XJS-Cabriolet: stripping all paint etc… . Would be nice to also revive the B-post finisher + badge. Items 5 and 6 on this picture:

Anyone has a clue or even better experience on how to remove? No fixings are visible inside or outside the car…

Regards,
Evert

Its probably high bond tape in both instances.
