The collection of Missouri Historical Society in St. Louis, Missouri includes the National colour of the 11th Regt. E.M.M. The silk flag is 60 x 84.5 inches in size with 34 white stars in the canton (arranged in 6 rows of 5-6-6-6-6-5). The unit designation 11TH REGT. E.M.M is appliqued in white letters on the fourth red stripe from the top. The flag is edged on three sides with a gold fringe.
From this is would appear that at least some EMM regiments were issued colours.
