No military marks. I think it looks like an older Helko crown. C H for Carl Helsper was stamped at the base of the crown It doesn’t have a marked weight and there is no DIN number on it. It does have a long bit and large eye squared in the back. It the last picture it looks like the German one could be tempered to where the CT edge starts. They started in 1844 as the Helsper Werkzeugfabrik,then ” In the early thirties, a partner named Kotthaus joined the enterprise, and the company became known as Helko (helsper / kotthaus).” But that is all I know so far. That, and discussion here. http://www.helkonorthamerica.com/about-helko.html Looks like A Big German Axe. Here it is next to a CT that weighs the same or plus an ounce.
