Remington 870 Wingmaster 1950's (serial and barrel code 23914V)

According to serial number, it is probably 1st or 2nd year of the 12 Ga Remington Wingmaster Model 870 which began in 1950. It was my father's gun that was bought new in Lincoln, Montana. It's in great working shape and hasn't been fired much -mostly was stored in a closet for 70 years. Gun shop estimated that it was worth $500 to $700. First $400 takes it. I don't ship so it is local Boise pickup only, as I'm not a FFL seller. First $450 cash and carry takes it. Just need to show a valid DL for a valid bill of sale. Thanks. I live about 1/2 mile from the crossroads of Eagle Rd and McMillan in Boise.
