Google is very bad at older posts. So I tried a Google search myself to verify it wasn't there, using site:www.ybw.com spelve. Nothing useful appeared, so tried Dogpile, and also nothing useful (I think Silkie and spelve as search terms), and nothing useful, so then tried Altavista, with search terms spelve silkie ybw, which produced this

Took just over a minute in total

More seriously, if you are having problems with finding something with very unusual search terms, and getting no results, give up instantly, and try another search engine, as they all have different algorithms, and you stand more chance of success than persevering with the original search engine.
