thanks peter,
i did not know of the existance of this virtuoso.
i think i have to change the thread name into marble virtuoso.
i am actually looking for the marble virt which belonged some years ago to joe, then to jon and finally to phil who sold it.
currently i own a celestial virt and the icepearl snakeskin virt which was pictured in the oversized hamer catalog.
would be great if the owner of that marble virtuoso is a hfc guy.
