I was recently given an early 1970's model Bear Minuteman bow. After cleaning it up I found it to be in pretty good shape with the exception of the upper limb tip. The wood laminations at the very tip, and I mean the first 1/32 of an inch, looks as though it has rotted away. It does not look like it is delaminating and it is about an inch away from the string nock. I can not find replacement limbs anywhere and I am worried about stringing it up in it's current state. Do I need to worry about it? Is there something that can be done to repair it? Please help.
