Hi, I am new to the forum, hoping to have posted in the right place. My question is about a buttstock. As you can see in the picture, there is some damage to the back side. Can you please give me some restoration tips, what to do with it? First of all, is there a good way to restore it, or leave it as is? /the idea is not to gt a "brand new" look, I would like to restore the end, if possible, without changing the appearance of the rest/. Thanks in advance!
