Please take this as a caution, rather than a criticism. Most vintage hubs are not designed for radial spoking. (I broke a Shimano hub across three flange holes a couple of years after I radially spoked it.)
Other than that, the bike is indeed a stunner, and nicely equipped.
If I am doing my tooth jump counting properly, that looks like a 3-3-4-4 increment pattern in back, consistent with the very common 14-17-20-24-28. I couldn't get the Campag. NR on my Bianchi to handle more 26T in back.
