Well, after watching this video:
http://www.ehow.com/video_2374818_irish-flute_.htmlI have decided that it is not an Irish flute... he says, "...also six holes. There are other types of flutes that might have a thumb hole - that would not be Irish style." Mine has 7 finger holes on the front, a thumb hole, and 2 random ones at the bottom. Also they are widely spaced - I can't even fit my fingers on it correctly
Oh also, the only way I can get any sound to come out of it is by blowing into the slit at the end of this side (see picture).
On with the search I guess! Getting closer...
