Have put this info now in the technical section.
After much searching I have found a very good alternative that I am happy with and could help others in the same position. The 320mm front discs that I was looking for with the large offset are identical in size to the ones that were previously fitted on the Bimota DB2 bikes albiet with a slightly different hole pattern on the carriers (Round) and discs material. There is a company in Germany who reproduce these discs with another pattern of holes in the carriers that is very close to the originals from Brembo. I think personally these are a very good replacement at the price (600 euros delivered with bolts) and what I like is the disc material is not cast iron so will not rust if you breath close to them. Maybe not for the purist but probably good enough for most.
Maybe this has been covered previously ........ I hope this helps someone.
See photos for info and fitment

great info for those who found a set of Corse three spokes for their bikes-- I remember back in the days when you found deep offset Corse disks you felt if you had found gold.
Good for you-----

Yes they are impossible to find and often the carriers around the bobbins are worn out. If someone has a set often they want a fortune. I thought these are very reasonably priced. The disc material is not cast iron but I see that as a benefit as I do not track my bikes. I hate my Corse as the discs are always brown with rust.
I have no association with the seller but I can say the service was spot on and the parts really look the business.

I really like the feel of cast iron rotors with a good organic race pad (Ferodo CP1).
While sintered pads on stainless rotors don't rust and work well for a while, I always end up with the rotors causing a pulsation after a while. I have religiously followed the manufacturers recommendation of bead blasting or surfacing the rotors to clean them up from the deposition type pads, but they all seem to do the same thing.
I have never had any pulsation/surging issues with cast iron rotors. They may rust. but it is pretty easy to keep them from doing so (ride your bike, and don't get them wet).

It might be easy to ride your bike in California and not get the discs wet but...
Over here in the UK* I always set my bikes up for wet weather riding, because it rains more often than not even in the summer months.
Which is probably why UK riders/racers are usually pretty good in the wet.
*I live in Cornwall in the deep South West of the UK, it's the warmest but also the wettest part of the UK.
Cumbria in the extreme North West of England claims to be the wettest but..
A lot of their water falls as snow in the winter months, whereas in Cornwall/Kernow we just get a F'kin lot of rain.

So you wash your bike..........get the discs rusty. Go out for a ride in the dry warm weather , come back and clean off all the bugs and get your discs rusty again...........or leave it dirty (Bugs and all). If you get caught in the rain on your way home.............what to do ?. Clean it off , put it in your heated garage , wait for it to dry. Put the bike on 2 bike stands and spin the wheels while applying the brakes to clean off the rust................ Even if I clean off the discs by riding the bike up and down the road , next time I come to look at it..........there,s the brown stuff again. Its a bit of a bummer !!!!
