Original WWII ear muffs. We acquired a box of original wire frames from our friend in Germany- and then we had the wool centers sewn on to complete them. Then we used old army blankets (origin unknown) for the wool and original fieldgray HBT tape to secure them. Originals muffs use numerous colors- gray, brown, fieldgray, fieldblue, and even red. The head band adjusts for different head sizes much like ear phones do. Used by all branches of the German military in WWII.
