You could be on to something there, Colin. (Edit: except it seems the Guzzi TS used a single disc ...).

In the meanwhile, a few thoughts, for what they're worth:
1. As far as I am aware, no Italian Ducati single used the combination of a Borrani WM2 18" front wheel + wires + twin discs. So it ain't from one of them.
2. Ditto for the Barcelona bikes (which in addition, at least in the case of my Vento, used 5, not 6, bolt discs). So it ain't from one of them.
3. The first 18" Borrani + wires + twin discs was the 750SS of 1973. But this was a WM3 wheel, not a WM2/1; and it's number is well known - 4777. So it ain't that.
4. Neither the 750 Sport or the 750 GT got twin discs. So nothing there.
5. The 860 GT did, in 1975. But it used WM3 steel Radaellis, not aluminium WM2 Boranis. So no match there.
