Date code of Y with serial number 924xxx doesn't match. Serial number 924xxx would be a date code of H for 1956 or maybe an I for 1957 (not every gun went out the door in serial number order).
Y would be 1971, and would only be correct if the serial number started with an A. If it's a 1956 gun, it will hve a lever safety. A 1971 rifle would have a tang safety. Either way, good gun (though the 1956 is much more desirable to collectors)!
