Well identified, James. I had found the blog post in question (http://ilovetypography.com/2008/05/26/sunday-type-frutiger-type/) and asked its author, John Boardley, about which font he had used for that glyph (there were nine other asterisks) but your identification chops were faster. I'll have to try out that Matcherator in the future.
