German Waffen-SS 'Winterbattle' pocketbook

In a very nice condition and very rare to find a German Wehrmachtsoldier pocketbook called: 'Taschenbuch für den Winterkrieg'. The pocketbook is dated 1942 and has the stamp of feldpostnummer 23059: (Mobilmachung-1.1.1940) 15. Hundertschaft SS-Sturmbann IV /1 dann 15. Hundertschaft SS-TK-Standarte 1 (Oberbayern) dann 15. Hundertschaft SS-TK-Rekruten-Standarte (Oberbayern)
