I don't know what these are worth in that condition. I do know a friend has one he has been trying to sell since after black powder season last year. Now his doesn't look new and it has a little rust. From what I saw it looked pretty decent though. I saw it when he was shooting it and I've been shooting with him when he has had it. I've never inspected it as a buyer though. He said it has a little rust but not much. Anyway, he has been telling people he will take $75 for it. I bought the scope off of it from him and at that time he told me if I wanted to buy a Simmons 8 Point Blazer 3x9x50 scope he would trade me. These are $50 scopes. I was tempted to do it but I decided I really just don't want another muzzle loader like this. Next one I get I want a stainless barrel and one that shoots 209 primers. He also mentioned that I was the only person that's shown any interest in his rifle. It makes me think if he is having this much trouble selling it for $50-75 that they probably aren't worth $140. However, your market may be different.
