Got this today. My first and only CSA button. Artillery button that looks like that had been in the ground long time. Actually ebay treasure but what the heck :P. We are not finding these in Finland.
Good stuff! The last one in the photo above is a general service Staff button. General service button might just be the eagle 2-piece, but this is a 3-piece "muffin-style" staff button. And it is a beauty.
