Since I'm not a real Galanthophile and I haven't got "the book" I noticed it on the AGS site where it's in the 2009 on-line show in class 87. I mailed Caryl and Michael Baron about it but it seems it's a slow increaser which is very hard to find...
Wim - I grow this & can probably spare you a bulb - I do not know anyone else, apart from Michael Baron, who grows it - it is a very nice, early elwesii with big flowers (the 'Snowdrops' book says January flowering, but it is always quite early in December for me) - send me a PM if you are interested.
