#30670, A Grade, 12, double trigger, straight grip, ejector, leather covered pad. 29" barrels (cut?) with .018 and .013 choke.

Things that strike me as a bid odd: pull off fore end, no city markings, just "Lefever Arms Co" and "Finest Damascus Steel" on barrels, "Lefever Arms Co" on both side plates, string of patent dates on trigger plate. Grade marking is next to the serial number on the barrel.
