At the Tulsa show last weekend I got a Stevens 44 1/2 rifle with the heaviest  Stevens marked barrel I have seen.  It probably left the factory as a 30 inch part octagon that was 1.375 across the flats at the breech and 1.25 at the muzzle.  Is this a Stevens number 5 or a special order?   The barrel has been shortened about a 1/2 in h at the breech to fit a different 44 1/2 action.  The barrel was cut to 27 3/4 inches plus the false  muzzle.  It was rebored from 32-40 to 33-40 by H. M. Pope in Jersey city.  It is dated 11/13/11.
Sorry no pictures at this time as the rifle is at Lee Shavers to have a new guide stater made.
I did shoot it on 11/13/16 its 105 birthday.
