Are you sure you don't mean "Walnut Hill"? There were two models with this name. One was a version of the Stevens Ideal, also known as model No. 49, made from 1896 to the 1930's and came in several calibers, barrel configurations, sights, and other optional features. One of these could go for $500 or more in Poor condition or $1600+ in Excellent condition. In the 1930's and 1940's, models 417, 417 1/2 and 418 were also called Walnut Hill. These were not as fancy or as scarce and values range from $180 in good used condition to $800+ if still in like-new condition.
Depends where you live, what model it is and what condition it is in Locally (new zealand) if in good condition usually about $500 - $750 (NZD) up to $1200 for excellent condition models with the walnut stock
