Camp Hut relics ID

[VaFredneck]

Recently pulled these relics out of a Confederate hut and have no clue what the big brass items are, could use a little help. The 2 brass pieces pic'd together were found together in one corner of the hut floor. The long telescoping item was recovered in an opposite corner, again no clue ? Have found carved Gardner's in this camp but this go around a cut roundball. The button turned out to be an Eagle I, it is an Infantry camp. Thanks for any input.
