I believe that the Eatmon 66 was designed by a bowyer named Del Eatmon. I think his kid was an excellent shot and used the bow to take some target championships. I think it was some NFAA championships, if I rember correctly.
Last I heard, Ric Anderson of Marriah Custom bows had gotten the forms and was producing a version of it called the Eastwind 66. From talking to Ric I believe it was a very nice shooting bow. I think it had a fairly long 21+" riser and short working limbs. Made for a very stable and quick bow.
Not sure if Ric is still making them. At one point he had some pics of them on his website in the album so you could check there.
