Thanks for the hint. I went through the barracks and hit "g" a couple of times and it turned up. I think Dikiyoba's advice was reversed, as when I compare Black Oak, composite and longbows, the longbow is the weakest of the three and composite and Black Oak are essentially the same. In any case, it was more important for completeness than for it's relative power, so thanks again. I did end up giving it to my sorceress for now.
