information from Karl Kristensen, Engkaebro 4 Stagstrup, DK-7752 Snedsted, Denmark on 29. Oct. 2005:
Ruigegno and Nuregino are in PCO notes described as two different, which I don´t think it is. I have never found describtions of those two. I have seen Nuregino offered for sale in an old catalogue, but there were no description.
