WWI German M16 Helmet in Concord, Ohio For Sale

It has remittance of a gold emblem on the left side of the helmet but I can't tell what it is. This German Helmet has seen battle with two bullet dents in the back and I'm sure one must have knocked him to the ground. There's no liner and any faint markings have been painted over. The inside head size is 7-1/2" X 9". The overall width is 9-1/4", Length 12-1/4" and 7" tall. This could have been a reissue helmet. It's a heavy, 2-1/2 pound, solid WWI German helmet that displays nicely. $150
