I have read col atwoods book " The daggers and edged weapons of Hitlers Germany" and his fascinating discoveries. IMHO the "Gonzo beak" pattern is an early etched pattern used during ww2 which was one of the patterns fakers later copied. I have heard that Spanish copies of third reich daggers are excellent so it makes sense that they were copied from existing known parts. It only makes sense that actual patterns for ww2 etches would by copied to sell these fakes. Forgers would not make up their own pattern, or they would go broke lol. My opinion is that the gonzo bird was a real ww2 pattern.
