The model 51 was the economy shotgun back then, and while mine held up well, parts these days are getting harder to find. I sold mine for $250 last year, and it was in pretty darn good shape. But it had a fiber optic sight, so it was not all original.
But I also wanted a fast sale, so..likely you can get more for a never shot model 51. $350 for a fast sell, $400 if someone wants it bad. That's my guess. This model did have its shorcomings, the most prominent being weak action bars, prone to early breakage.
