This is a version that you don't often see! It is a great looking original 23mm version coat size Civil War Rifleman Eagle "R" button. This is the button that would have gone down the front of a Rifleman Officer's coat. The eagle on the front of the button has the "R" in the shield that denotes the rifleman branch of military service. As you can see this is the distinct face variation that was only made by Robinson, Evans and Dale. This style is listed as RF20 in Albert's button book and as RF222a1 It has beautiful color to the brass on the face and the back has the correct Civil War "* R&W ROBINSON *EXTRA RICH" backmark. This is a very nice looking Civil War rifleman Coat button.
