I looked at those previously Jim, and it was the different spider made me go of it.
I know theyre mtb, but i cannot say 100% that theres not a range of spiders, given these are 130mm bcd,which suggests road. But these are beefy and i wouldnt think a roadie would use such a heavy bit of kit.
Reverse looks too exact to be anything other though and its totally flat.
Only provision for a single outer and a (looks like)74mm bcd inner
