F-285 backpack with the traditional pony fur front and leather straps. It is maker marked on the back with "Z&M, Krakau W." Has an inner compartment under the lid with a button. The inside devices that hold the shoulder straps in place are interesting. This does not have its shoulder straps. The remaining black leather straps are in good shape and show some age, and the one on the right side, and the center strap are broken at the tips. This is named on the back. Neat piece of WWII history and made in what was certainly occupied Poland.
