How I check if Alpinas are genuine?

[martinclan]

There are a lot of Aplinas around for sale. I know from previuos discussions that many of them are replicas. How do I tell if a rim is genuine?

Thanks

they are only 16 inch mate, have 20 spokes instead of 19 on most replicas and will have ALPINA written in the centre and offset Et28

they are made by Ronal and this will be stamped on the back of one of the spokes. The sizes are either 16x7 or 16x8
