The Antics Stock system shows a couple of kits in stock:
HMS Brecon
HMS Exeter
and there are some made up models listed ambiguously but not displayed on the website, so you would have to telephone the warehouse to get someone to check the shelves:
Aradu (Nigerian Frigate) - I saw this myself earlier this year...
HMS Diligence (ditto)
Engadine, Ocean (CVL) & Olwen. I haven't seen these three myself since before lockdown, so these are not likely to exist being victims of selling with generic stock codes or the wrong stock number.
