Is there a definitive way to tell between KMags made in 1970, 1971 and 1972? Is the accent stripe the same in 70 and 71 (a dark wood) and the stipe in 1972 a more reddish colored wood. I have a bow that I believe is made in 1970. It has a dark wood accent stripe and no bushing for a stabilizer in the front of the grip. Did 1971 and 1972 bow have the bushing? Can't tell from the DVD Bear Catalog. Thanks for your help. Dave
