Rest of the pictures don’t show the axle, just the Quarq cranks and close-ups of the chainrings. But here’s the listing if it clarifies anything.

Sorry, I don’t quite understand the question. There is no BB, I’m asking what sort of BB might be best (or least worst) for this somewhat mismatched application should it turn out I bought the DUB version. But it sounds/looks from eric’s photos above like maybe my first half-asleep instinct was right and that is GXP which would be great as it’ll be a straight swap as there’s a GXP BB in there at the moment.

Can’t cancel the order, they shipped it while I was asleep
