This auction appears to be for only two wheels instead of a full set. The Chromadoras offered as an optional wheel on the 1988 Mera were 15" wheels in a 5 x 100 lug pattern with a 7" rim if I remember correctly. Based on available information, these are likely original Chromadora wheels without the large plastic center wheel cover. The problem is what to do with only two of them. They would be good for spares if you already have a set. Finding a full set of these wheels in good/excellent condition is difficult and/or expensive so these could be a good buy.
I can check actual measurements on an known original Chromadora wheel if anyone needs the data for confirmation purposes.
