A carbon fiber warped barrel on an older rifle is highly unlikely.

Hammer forged bull barrel;
the finish is a sparkling spiral milling.
This is an image I located of a hammer forged barrel

Bye the way, the spiral marks are not as a result of milling.
They are tooling marks from the hammering process.
