A friend of mine gave me five Bear arrows. They look to be full length and made of cedar. They are painted a tan color and have green Bear Razorhead broadheads on them. The only writing on the is between the crest and the fletch. It has the Bear logo and says Bear Cedar. They also came with yellow and green vanes and a blue nock. My question is, what year did Bear produce arrows like this with the broadhead on it? The vanes are falling apart, would it be wise to strip the old vanes off and replace them or should I leave them alone. Thanks, Tripper
