Dorman Smith DBs, where they have broken into the busbars between the main switches and the MCBs to put the contactors in series. Similar setup in both boards but obviously left one 3-phase, right one single-phase. If you're taking them out I'm after some like that.

I was hoping one of those mcbs had the fault current limiter fitted to the outgoing terminal. Looks like a folded bi-metallic strip you could buy separate and it essentially increased the breaking capacity. Just trivia.
