Assuming you want rim-braked, silver finish, Shimano cassette compatible, 130mm OLD QR axle type, I suggest VO touring hub. A few here have tried them with apparently no negative feedback.

Most have had good results with Deore/LX/SLX/XT level Shimano Mtb rear hubs. These are fairly inexpensive, but nowadays most come only in disc version (which IS still compatible with rim brakes), black finish, 135mm OLD QR (older Mtb spacing) and 32h. Tourers normally opt for 36h, and 135mm spacing builds better wheels than 130mm OLD (normal road bike spacing), which is fine for most as they also desire lower gearing available with Mtb components.

If you built a front wheel with DT TK540 for a Bianchi then you probably need 700c wheeled / 130mm OLD rear spacing, and to match an old PW front hub (almost certainly rim brake compatible in polished Al finish) you'd want a silver hub, available at <PW pricing, which narrows choice considerably. The VO hub has replaceable cartridge bearings which are potentially longer-lived than the less costly Shimano hubs with loose balls in cup and cone. Under normal usage the Shimano hub's cup eventually becomes eroded with a track worn in by the balls, and since the cup is pressed in, it's not user replaceable, so the hub must be replaced, meaning a wheel rebuild required. By this point the rim typically has a lot of brake track wear and needs to be replaced as well, so the inexpensive-but-disposable Shimano hub approach is actually fairly practical.
