Thanks..... The link is in the blurry picture that you cannot read unfortunately... It is from a USGI who landed in anzio in 1944 The same year the flak unit was transferred to Italy.   ... I have his scrapbook with a bunch of newspaper cuttings and some letters back to his parents... He was in Italy the same time this flak unit was ... All the plates came from the same gi's estate.... I don't know where he obtained the other two plates...

From the U.K.? British?   Close look at post #4, I am ten thousand percent sure that what you have is a really cool piece of shrapnel from a No. 36 Mills Bomb.   https://en.m.wikipedia.org/wiki/Mills_bomb  

Here are some brighter and better photos. I haven’t taken it out of its display case but thanks for the tip!

A few other photos

can you post a close up of how the attachments work?

I recently picked up what I'm told is a French Model 1823 Lance, and from my brief research that appears to be correct. It has the different  length langents on the lance head (one being very long) and the rectangular holes for attaching the pennant. Both the lance head and haft are stamped "GD" with crown above. Can anyone tell me what that stands for and the dates it was used? The pennant on the lance measures about 30x12 inches and has some mothing. I'm sure it is not original to the 1823 period, and the leather cord attaching the pennant to the lance is certainly modern.  But I'm told lances like this could have been used later in the Franco-Prussian War and even WWI. Is that true, and if so could the pennant date to either of those conflicts, or is it simply a later but still old reproduction? Any info or thoughts about the lance or pennant would be greatly appreciated. 

Don’t photograph it on white unless you have lots of light. Use a medium gray background inside or outside in the shade. That said, though very dark, I too think pineapple.

can you post a few more pics of it? Hard to see the shape. I think you are right though, it maybe a pineapple piece.

Infanterie-Regiment Kaiser Wilhelm (2. Großherzoglich Hessisches) Nr. 116   It's for a One Year Volunteer by virtue of the Red and White twisted Piping, Red and White being the State Colors of Hesse. It must be an earlier one as by the start of the Great War, this regiment's Shoulder Strap has a Monogram, for Wilhelm, Wilhelm the  II. So maybe before the regiment was granted it's Royal Title??? Not sure when it was granted, sometime in the 1880s????   Here's the Field Grey version showing the Monogram.

Weaning the Field Grey, they are of the 7th Panzer Division.
