Brackets Termi????

These came into my possession recently with the suggestion they were Ducati Termignoni Brackets, but with no idea of what bike.
They were in a box with Termi tape on.

I thought at the time it was more likely that somebody at some stage had put their standard brackets in the Termi box after fitting the Termi brackets to their bike, but on looking at them again there are none of the usual part numbers etc that Ducati normally have stamped on everything.
And they do look basically unused.

They are Aluminium and exceptionally lightweight.

Does anyone recognise them?

 

Well done ChrisW, many thanks.

I think that settles it that the big bracket is a stock 899 1199 part.

I'm afraid there is no prize

 

You know I like to do thinks the hard way.
I'm more likely to build a complete bike up around it by buying all the bits individually from Ebay.

 

Can anyone identify the pair of smaller brackets?
I can't find any similar being sold for an 899 or 1199

 

I think Lady Nasher would go mad Fire 3.5K.

 

Thanks again ChrisW

Now I know they are nothing special I won't mind adapting them for another use.
