It's been a while since I updated this thread, but I've actually gone on to do training and race accreditation at Herne Hill. Also made some minor mods, I managed to find some Dura Ace FC-7600 NJS stamped cranks which I stripped and polished
They paired perfectly well with a Campag Centaur BB, I read from differing sources that the taper on these DA cranks is not JIS, in any case this BB gave a 42mm chainline and the tapers fit snugly just right.
