First, and FOREMOST, I give 100% of the credit to Jan Still for the pictures and the excellent thread that was presented on his forum, prior to the assault that deleted many of these excellent posts. He started that thread and provided the pictures. This G Date has no flutes (or chamfer as Ron calls them). As I remember his article, the K dates exhibited a crimp groove that was from one of the earlier manufacturing processes and the flutes were simple added to remove the crimp mark. Some K dates will have the flute AND a remnant of the crimp mark. This G date receiver just missed the step that added the flute so the receiver goes all the way to the end with no flute. Thanks to Jan for bringing this interesting subject up and allowing me to share this on John Dunkle's Luger forum.
