What's the easiest way to make your infantry impression an artillery impression for Winter Quarters?  Just swap the buttons on your blue grey wool Richmond jacket.
 
These buttons are excellent reproductions of the crude locally-made artillery buttons commonly dug at ANV sites.  They feature an uncoated red brass or copper face, not bright yellow brass, and a tin back just like the originals.  
 
Buttons will come in a sets of 11 and will be mailed to you.
