Sadly, I believe this to be an accurate estimate of value from your description, somewhere between $400 and $4,000. Really good pictures, with all the details, would be a big step towards narrowing this estimate.
In such rifles, there often remains a significant subjective impact on valuation, even after pinning down all the details.
I am helping an older relative reduce his collection. Some of his nicest custom rifles have never been hunted or shot much. They are bringing in less than half of what he paid just a few years ago, and often less than he paid for the stock blank. On the other hand, some of his old Winchester 94's are bringing in several times more than he paid for them. It is a fickle market.
