Leather double breasted deck jacket as worn by U-Boat personnel as well as by other KM crews. 2 lower pockets and 2 side pockets, gold KM buttons. The interior is lined with artificial silk and has snap tabs in the arm seam area for removable sleeve linings if not for full interior lining. The leather is still supple and does exhibit white powdery mold in spots as can be seen in the photos. This should be able to be treated and removed as it does not appear to have caused damage as it is on the surface.
