Looks like Alaskan Yellow Cedar to me, and features a nice Thunderbird pyrography design. It does have a couple dings as you might expect on a flute made of softer wood of this age.
Overall length is 25 1/2. The bore is 1 1/16 in diameter. You can take my word for it, or just listen to it on the following very short YouTube video. This video is of THIS EXACT flute.
