I was reading about a Belgian Gunsmith recently by the name of Mr. Harald Wolf . This gentleman made some pretty impressive rifles in some rare German calibers and it is my understanding that he is the man responsible for bringing back the .500 Jeffery in 1986 after which it became popular due to Mr. Tony Sanchez Arino ( one of my favorite big game hunters of ALL time ) using it successfully on elephant. Mr. Harald Wolf apparently run a company called Mastergunworks in Belgium. But l can't find any trace of him anymore. Does anyone here know if he is still around and making rifles ? He even used to run a rifle Magazine called " Hatari Times " . He seems to have Vanished . Does he have an email address or website ?
