I think the band versions had the older thread standard so they work with old-fashioned Simplex bands. The braze-on versions were designed to mount to standard Campy fittings, and thus used the correct threading for them.
Simplex band clamps are on ebay, but prices are a bit more than I'd like to spend, and you still have the threading issue. There must be other band clamps that match the square-based Campy braze-ons, though I have yet to find one.
