I did notice that.  The way “beavertail forearm and pistol grip refinished” followed my “mint condition” make me assume the metal is represented as original.  The metal does look perfect.  Are there places, maybe beneath the barrel, to look for honest wear?  Were model 21’s lacquered like model 70’s or similar rifles of that era?  Many 1930’s or earlier Winchesters had receiver bluing that was prone to flaking, which can be an indicator of original finish.  Is this true for 21’s?  What would be a beginners crash course in items to look for when accessing a 21?  On this shotgun a refinished stock could honestly be more durable for hunting than a lacquered stock but refinished metal completely hides whether its a refurbished completion gun or a flaking receiver.  

Any insight would be greatly appreciated.
