Bore should be .729, up to .739, over .739 it's out of proof.
Chokes are what they are, they could have been opened along the way but if they are both close to .000 (CYL) check to see whether the barrels ave been cut.
Barrel length would most likely be on a .5 inch increment.
Wall thickness should be checked, especially if the bores are close to .739.
Finally, the barrel blue looks OK and having the "bits" recased or reblued might be more expensive than it's worth.
If everything else checked out and the stock fits just have the action tightened and shoot it for a while before putting more money into it.
