Post this question on the Savage collectors page and you'll be more likely to get an answer. I will note that it's not particularly collectible in any case (.300s are very common) and value will be further decreased if the rifle was not factory drilled and tapped. You can determine that by seeing if the front receiver ring has the Savage marking on the top (with the holes drilled through it - thus not factory done) or on the side which means the holes are drilled without disturbing the markings. Condition also matters. In good condition (relatively little wear to bluing or wood, most of the case color on the lever), you're likely looking at $450 on the low end to $600 on the high end unless it's a rare configuration.
