Bud hitt is still around, although he is in his '80's. He may be able to fix that bow. I have his phone number but I will not post it here, Send ne a PM and I will give it to you.
Two things stand out that identify it as a HIT Bow.
1. The way the limbs attach to the riser. Under that cap block there is a bolt joining th parts together.
2. The cam limb. The way the limb has a bend in it on both limbs. Bill Stewart also made his limbs this way.
As rough as that bow is, it is a collectors item.
He is now into trophys and plaques.''His website is:
