I did a bit more research and and made an inquiry into my Hungarian M49/82 Zeltbahn-Poncho over at the online military collector's forum, Wehrmacht-Awards, and hit the jackpot. I would like to thank Charles for his information and his offer to share several photos from his personal collection that I have included in this posting.
The zelts from WW2 used an oval grommet at the "point" of the zelt that was designed to fit over the bayonet on the end of the rifle, (M95 Steyr Rifle). The rifle and bayonet were used as the pole, with a helmet over the end to keep out the water.
Post WW2, the grommet was changed back to a round shape to accommodate the long spike-type bayonet on the M91/31 Mosin Nagent rifle. Again, the rifle and bayonet were used as the pole, with a helmet over the end to keep out the water.
After the 1960's, the Hungarian Army switched over to the AK47 rifle with a blade type bayonet, so a tent pole set was issued to match the round zelt grommet.
Since my zelt is post 1960's, it would have been issued with a take-apart pole set that would have been carried in the assault pack.
The following three photos were taken after WW2 and show the M49 zelts in use (the earlier version that my M49/82 is patterned after). It is interesting to note that there are several WW2 German Waffen SS, pea-dot pattern zelts being used along with the Hungarian zelts. You can also see that the pole in the first photo is actually a tree branch! This would lead me to believe that these zelts were often used without a pole set............... You can also see how a large, tent sized "fox hole" was dug out under the tent to give more head room and to accommodate the extra length of the rifle when used as a pole.
