My friend and cohort John Chandler (he plays in a Guided by Voices cover band which makes him 10-times cooler than everybody else I know) alerted me to the following:

"Caleb Klauder of the local band Foghorn Stringband had his 1939 Martin 0-17 all-mahogany guitar stolen from a car in NE Portland on Friday Oct 10th. Also his John Sullivan F-5 Mandolin (#79) was stolen too. "These are my Work Horses, My Life,’" Klauder says. "I play every day for a living and need these back."

So there you have it: an ABP for a mandolin and guitar. If you know anything about it, please do let us know.
