The S. Sm is S. Smith, don't know why his name is on them unless he made the barrels. The numbers match on the barrels and the receiver/trigger guard. I've looked at the barrels under different lights with a magnifier and can't see any sign of damascus or sleeving. The 500 ex would be 500 express I would think.
