During WW1 Allied soldiers reffered to German shell that came over as whizz bangs. I take that this would be the 77mm, was the refereal of a whizz bang a shrapnel shell or a HE shell or both? What would a typical shrapnel or HE round look like and what markings would they have. I was thinking about adding one to the collection what would i pay for a good one these days. I saw this on e-gun, is this the correct color for it.
