Austrian Drilling, 16 ga./9.3x72R cal. combination hammer gun.  Serial #5187, mfg. Austria.  Unknown maker.  Good condition.  27 ¾” shotgun barrels have shiny bores with slight traces of pitting.  2 9/16” chambers.  Rifle barrel has strong, sharp rifling with some light pitting.  Barrels have 70% blue with traces of corrosion.  Front sling swivel has been re-soldered. Rear flip-up rifle sight is a replacement.   Barrels are made of Krupp steel and Nitro-proofed. Frame and lock plates have attractive Germanic engraving  with deer and scroll scenes.  Lock screws are dinged. Stock and forearm have been sanded and have approx. 50% finish, checkering is worn with several handling dings.  Butt plate appears to be a replacement.   Underlever action locks up tightly, hammers cock nicely.  Single set trigger is not working.  Nice old leather sling. Probably an “apprentice gun” and undoubtedly a GI bring-back.  C&R OK.
