Setting up my new ring doorbell with very old chime

Hi guys I’m new on here. I purchased a new wired ring doorbell But my council flat has a very old wired doorbell and chime(see images). I was wondering if anyone knows if I gotta buy a plug in ring chime and I think I need some sort of pack to install the proper voltage unit. I think I will need the plug in chime for a socket near my front door but what about wiring it up? I would appreciate if anyone from Scotland had this same problem? I think I need something else to wire it up correctly with the correct voltage and that. Thanks guys. I have just found out new users can only upload one image so I am sorry if doesn’t help. Pardon my door frame I’m In the middle of decorating thanks.
