The Wehrmacht-isse "Zeltbahn" shelter quarter was issued as part of a set of gear called Zeltausrüstung- tent equipment. According to the German military regulation HDv 205/1, the Zeltausrüstung consisted of one Zeltbahn 31, one Zeltleine 92 (tent rope), one Zeltstock 01 (tent pole) and 2 Zeltpflöcken 29 (tent stakes). Many collectors and reenactors today want to have 3 of each of these but that is not how these were issued and it makes little sense as it takes 4 poles and a minimum of 4 stakes to erect a tent.
Notice that the Zeltausrüstung does not include a bag for the pole and stake. The 1895-pattern Tornister as used in WWI and then through the 1930s by civil, political and paramilitary organizations did have a bag for tent accessories that strapped into two loops inside the pack. WWII-issue packs did not have these loops inside and did not include a tent accessory bag, these were not general issue items in the Wehrmacht. Presumably it was not considered necessary to issue a bag for the purposes of holding the rope, 1 pole and 2 stakes.
Here are some original examples of the Wehrmacht-issue Zeltstock 01 tent pole, from a member's collection.
