AM.2:  I think that's the local vernacular for Osage or "Boe-Dark", or as the french say Boise-d-arc.  I may be wrong, cause I heard it also called Hedge Apple or Horse Apple.  
What do you say Dave?
By the way AM2, nice bow on your other post.  It looks very Mid-Evil, and as my grand-dad used to say, "Hell for Stout".
