Here is a portion of a letter written by James B. Lockney of Company "G" of the 28th Wisconsin Infantry

Little Rock, Ark
January 13th, 1865, Friday

"...Capt. Kenyon was in Com. We reported at the Arsenal, where we had to wait about an hour. This was the first time I ever was in the grounds & I was glad to gain admittance. I found there were several batteries in order, ready for instant use. They range from the heavy 20 lb. Parrot gun of a long range to the light 12 lb. brass howitzer for Cavalry use or the smaller rifled steel gun that throw a 6 or 8 lb ball. In all there are some 35 guns in the yard."

It would seem to suggest that the guns of the 1st Indaina Cavalry "the smaller rifled steel gun" were in the Little Rock Arsenal in January 1865. Pvt Lockney had been previously stationed at Pine Bluff in 1864 and would have been well aquainted with these guns.
