I find it kind of strange that you did not notice it if that spot was there when you bought the bow. I’m with Max, looks like someone tried to sand it away.
I did notice the uneven sanding at first but the delam spot in question wasn’t there at the time.
A little more backstory as I do think it pertains to this issue: I think they either forgot about my order or the previously mentioned health issues started up after I had placed my order. I received my bow approximately 18 months after my order date when they said it would be more like 6-12. I have never heard a bad thing about these folks and when I simply reached out to inquire about my bow, they were quite short and borderline unpleasant. You could feel the tension in the correspondence and conversations we had. I could tell they seemed pretty stressed and when I saw the uneven sanding, I didn’t want to bring it up as it seemed petty at the time. When I received the bow a year and a half ago, the bowyers handwriting on it seemed very off and the email I received back from them yesterday confirmed my suspicion. Unfortunately, they said I must’ve hit the bow on something and more or less said this issue is my fault. I’m pretty sure this is one of his last bows he’s made and you can tell something is just off on it compared to his previous work.
Anyways, not here to complain about them. Just trying to show why I didn’t pursue some initially minor issues and now I’m paying for it I guess. Just hoping I can keep this issue from getting worse.
