The "anyway you want it" triggers which KY is dealing with were called the "twin-single"--either trigger being capable of firing both barrels in sequence but the selection for first barrel being in the choice of trigger just as in "double" triggers. They could also be pulled front to rear and rear to front to fire respective barrels just as in the case of double triggers. At least that's the way old #278X works. Other than the name, Utah's description is correct I think. Don't see the "anti-crossfire rib and the horseshoe forend every day either.
