Savage Model 720, 12 ga, auto shotgun.   Serial #53011.  Very good re-finished condition.   26” plain barrel has clean shiny bore, 90% blue.  2 ¾” chamber, choked IC.   Receiver and trigger guard have very good re-blued finish.  “US” marked on left side.  Stock and forearm have excellent finish with few tiny marks.  Browning long recoil action.  Nice example of a civilian autoloader recruited for military service in WWII.  C&R OK>
