Pack / Tornister WH Germany WWII

For sale comes this very nice unit marked pack from the German Army. The condition is still very good. The leather is soft. The fur is also 99,9% on. Made was this pack by a company in Vienna in 1941 C.Budischowsky. The owners name is written on the back part of the bag (Fischer Karl and a number?).Like I meantioned before there is a unit marking on both inner sides of the shoulder straps 2./Pz.Abw.13I (Antitank unit).Strange is that both shoulder straps were made from a differend maker and in 1935. Maker is A.Fischer in Berlin!!
