I came across this on an auction site today, nearly didn't click it because it at first glance it looked like a typical 3,7cm. But the case is actually a German 6cm naval one. So it must be quite a bit bigger.
I don't think the case and projectile belong together, since the 6cm projectile I have for this case fits very loose, and this seems to fit very tight.
Any ideas about what this could be?
