My artillery unit has decided to galvanize as Gwinnetts Battery D 9th Georgia artillery Batt. I've had conflicting opinions from some of the mainstream sutlers about how common sack coat usage might have been. I have the union artillery shell with all it's red tapes and a plain union sack that I use in warmer weather. What are your thoughts to using a grey sack for those few times I galvanize?
