In reading posts under "Paradox and Bore guns," this website, I noticed that someone mentioned Hatari Times magazine, so I looked into it, having not known about it before. In doing that, I noticed that a Harold Wolf wrote at least one article for that magazine, and in reading it, I noticed that he is a very experienced double rifle builder, writing technical details in gunmaking, so I am highly interested in reading any and everything that I can find that he has written (can anyone help with that?---what issues of Hatari times did he write in?) Anyone know about any other experienced double rifle builders having written good informative articles, especially on gunbuilding details?
