I have what I think is a German Naval 10.5cm HE projectile. It has a sintered iron driving band, a threaded plate for the gain and a threaded hole for a base tracer. The projectile looks to me to be of a first war design that has been modified, perhaps prior to the second war. There is a faint naval mark by the stamped numbers but no date and no other marks visable. I've not seen this type of projectile before, can anyone offer any information or reference on it?
Many thanks
