Please describe the item in as much detail as possible. Detail does not mean "in good shape" ,describe how the wood is, how much blueing (% of original finish left) there is etc., and anything else you see that may be helpful. Tell us all marking, words, and letters anywhere on the gun...
From another thread:
"Springfield" was a house brand of Savage/Stevens, for their inexpensive lines of firearms, and those sold in bulk to some chain outlets.
Savage/Stevens guns may have a date code on the underside of the barrel, that has nothing to do with the serial number.
Look for a circled letter, usually placed between the forend stud and the barrel hook.
A thru X, from 1949 thru 1970.
But an expert can tell you much more if you post pictures.
Stevens dropped the Springfield name on shotguns in 1948. It should have one of several versions of the Stevens name on it. The date code which started in 1949 is located between the trigger guard and the hinge pin on the bottom of the frame. It will be an oval with one or two numbers and a letter. The letter is the date code; i.e. A = 1949, B = 1950, C = 19151, D = 1952, etc.
