I don't know, I know the guy who had them was going to take them to Japan or look for a potential buyer there. He said he showed a photo of them to a shop in Japan and the owner nearly had a heart attack.
He was asking $10k+ from memory. I looked into restoration of them and got told they were beyond repair, you would use them as garden/garage ornaments only. But he was convinced he'd struck oil (seller) and I didn't even bother trying to offer him a reasonable price. (I want the wider version anyway).
Pretty sure they were fitted to HS30 00920 when sold in NZ.
