A 1-9 twist bull barrel unmarked is likely Model 1 Sales or a J&T/Doublestar.
Do you know what bolt face depth it's set for?
If it's .125", I wouldn't waste any time with the barrel as it's a Model 1 Sales "6.5 Sporter".
If it's .136", maybe consider finish reaming it, but I would personally just get a known barrel from a known source with a 1/8 twist anyway if you plan to shoot distances.
If you just want a beater, feel free to invest more time into a poorly-reamed unknown, or just get a new barrel.
BTW, that's a beautiful chamber cast.
