Stevens model 235

Could anyone tell me the value of a Stevens 235 sxs external hammered shotgun in about 85% finish and tight lockup. I have no way to post pictures but thought someone could tell me ballpark figure. Also were there any of this model with damascus or laminated barrels and were they serial numbered and use 2 3/4 shells? Sure have a lot of questions don't I. Any info is appreciated.
