This traditional boomerang is No. 2 / 25 from a limited production set made by Lorin Hawes to commemorate the 25th anniversary of the first M-17 that he made in 1959. This is No. 2. No. 1 went to the Smithsonian Institution. Lorin Hawes made this set after it was recommended by Ben Ruhe. This boomerang is in mint condition. I have never thrown it. The underside has Lorin Hawes special logo on the underside of the elbow and the words " Number 2 of 25 of a limited series replica of the first one made. The boomerang is stored in one of Lorin's socks and it includes an original throwing instruction sheet, folded as it was in the original production. Also there is a letter included that explains the history of this model and the story behind the 25th Anniversary set. It is also signed by Lorin Hawes and dated 1984. The letter is double folded to fit in the sock and it has some creases and tears as expected. A very nice and rare collectible. I purchased this one directly from Ben Ruhe and have never seen another one.
