Rotor 3d24 non drive 172.5 crank arm

I don't suppose anyone has one of these about? I sent the crank away to velotech to replace the DTT bolt. It's to badly damaged to replace apparently. Can't rethread it. My own DIY mistake.

My plan was to buy a new crankset to use with type s p2max pm and then buy a new p2max as its pretty old. But the designs have all changed, new ones won't fit this. P2max are to come back to me with a "fair price" for a new crankset and pm. I suspect their fair and mine may be some distance apart.
