With an unmarked, unknown barrel, I would simply check the twist rate myself. I trust makers like Obermeyer, Kreiger, Schneider, Lilja and so on to sell me a barrel with the twist that they stated. If I were to buy an unmarked barrel at a gun show, or from someone I didn't know really well, I would check the twist myself just to make sure. Even honest people can make mistakes.
