Brand new to me. It's an L579 in .243, with a serial number less than 1106x... Do folks normally say what serial nos they have on forum? Bofors steel barrel, and longitudinal grooves on the cocking piece instead of checkering. Flat and checkered bolt knob, and a half moon floorplate release inside the trigger guard. I think it's a bit customized, with a jeweled bolt and contrasting fore end, but I don't know if it's factory or later. I'm in love!
