German WWII Luftwaffe Flight helmet. This is the model K33 and is very nice condition and shows little use. Brown soft leather shell, has two lower chin straps, one strap has the markings on it L.B.A. 15143? Buckle clean and show no rust, fitting also clean. Full sheepskin liner has inner cloth tag as well with the RBNr number. Adjustment strap on the top. About a size 58. Very nice!
