I suspect the obverse logo is the result of Pack not wanting to overlap with the reverse etch, which seems to take up a lot of blade space. I've seen this on special order presentation daggers so I suspect the same could be true on a special order bayonet.
I too have the same question about why they would have a cavalry charge against a machine gun emplacement. Initially I thought it might be some sort of battle recreation with the Polish since I remember reading about Polish charges like that, except the horsemen clearly are wearing German stahlhelms. The detail is excellent & you can even see the decals on the helmets so they're definitely German soldiers on both sides. Really cool piece.
Beautiful & rare bayonet John, congrats brother.
