In TW's book that encompassed the contributions from many individuals, with some of them very, very enlightening - that the average individual might never have a chance to see in person. That said, it also has some flaws and omissions including the bayonets section that had some indisputably bad information/examples. And unless I'm mistaken the only pictures of a "Heinz Brenner etched SS bayonet" only showed a part of the blade. Best Regards, Fred
