The 1273-2S is a service replacement for the original 1273 and 1273-1 that were used on '57 312's. They were built after the '57 production run and after the 1273-1's ran out of stock. Not quite as valuable as an original '57 run 1273, but I'm sure is still considered correct for a judged show car. There are also minor outside appearance differences like the arced slot in the secondary throttle lever instead of the original straight slot. Also the bowls had thicker reinforcement to prevent warpage after installing them.
