I was just engaged in trading emails with the author, Michel. He mentioned he is working on a update and translation that he hopes might be ready sometime in 2013. Much as I would like that, I won't hold my breath. Then, whenever it gets done, I'll be pleased to see it.
I have his 1st book. I struggle with the French. He is very thorough. I know that he is a major gun writer in Belgium. He is certainly the leading expert on all things Pieper.
If you could. Next time you contact him. Ask about the Modified Diana's with Pieper woven into the damascus. I have a theory, but would love to hear his take on it. When I make it back to Belgium, he is one of the people I want to meet.
