Do you know what these wheels are?

I've been looking for some turbines for my e9 and have come across these. I cannot see any markings to indicate the make. They are 15 x7. They came off the drive car of the BMW wrecker (it was a rare e3 2500) who closed down 20 odd years ago.

I believe those are an Alpina knock off wheel, perhaps made by Ronal. Stevehose has a set of these (I think) that he bought from a forum member. Pretty rare wheels.

Thanks Ohmess,
It's been difficult trying to research them on the Internet. Nice to know that someone else has a set. They are amazingly light at 14.7 lb (6.7kg) each.
