Been looking for some sort of verification. Some look like a Z and some do not. Appearing to be a Regimental brooch from a Gulf War victory parade. Odd I cant (yet) find a replica. Which in and of itself is odd. But also the designer is named Marina Killery.

Still on the fence of it actually being a Z. Getty images are usually best and thise all appear to be a Z and only a Z. The rest of the brooch seem to be ornamental backing only. This one is also on the hard side to find results on.

So, Ill go with it being a Z. I stand corrected. But all the Z in the pics being related. I doubt Ill be able to find enough info to tie those all together with any meaning other than shape alone.
