Don't know if you were aware of it but you own a rather unusual smooth skin Eriba. (like Islay Corbel's ). Nearly all Eribas from around 1985 to 2000 are dimple finished and the smooth skin was introduced with the newer generation of vans around 2001 onwards until production finished in France in 2010.
