Seeing as I have plenty of time on my hands for the next few months at least,the Monkey and I are looking for something to do. The model 46a that I saw last week with the wide forend keeps haunting me. It just felt too good. But it has a couple of tang cracks along each side of the tang cut out. How hard of a job is it to repair these problems? What way would you go about doing it? Any good reference material out there?
