Engraving and non-ejector suggests it is a model 116, likely made in the late 1950s, early 1960s. A mid-range gun then, in terms of price point. Much less expensive than the AyA model 1, more expensive than the Model 2. Medium game gun, usually built as a less expensive version of the AyA signature model 53.

Value now? Whatever a seller is willing to pay. Same as any other used shotgun.
