Here are some pics of an original Henry Cartridge box from 1864 and a reproduction that I had made.

Here is a little info on this cartridge box from: (it is the second one mentioned below)
Henry Cartridge boxes: (From article: Henry – Victory through rapid fire, Andrew L. Bresnan, M.S.
The National Henry Rifle Company)
There were two types of cartridge boxes for the Henry. One of these looks very similar to the regular Springfield box of the Civil War. It has an implement pocket sewn to the front. It is covered by a large flap. Instead of tins for the inside, the Henry box contains 4 wooden blocks. Each block was drilled to contain 35 Henry cartridges. These blocks were stacked on top of each other. The bottom of the box was open. When the top block was emptied, it was removed and pushed up through the bottom. This moved the other 3 blocks up into position. The blocks were held in place by means of a spring on each side of the box. It also had 2 leather straps that went around the bottom of the box to insure that the blocks did not fall out.
The other box for the Henry did not hold as many rounds. It is possibly the rarest cartridge box of the Civil War. This box was manufactured by the New Haven Arms Company in 1864. The black leather flap measures 7 inches across and is embossed with the standard "US" oval 3 inches across. The flap is pointed like a shield at the bottom and measures 4.5 inches from point to top of the box. At the bottom left hand of the front flap of the box is marked "Henry Arms Company 1864" in 1 and three eighths inch elongated rectangle inspector's stamp. The back of the box has two, three-quarters of an inch leather straps riveted to the box four inches long for fitting over a cavalry or infantry belt. The flap affixes to the box by a brass vinule in a three-quarter inch leather strap. Inside the box is a staggered row of linen loops with places for 16 cartridges. On the outside of the front box, underneath the flap, there is another stitched row of 8 linen loops for cartridges. To the left inside the box there is a rounded space with a leather strap with a cut out for a Henry rifle tool. The box itself is 6 inches by 3 inches. It is 2 and a half inches deep and 2 inches wide. This box is pictured in Dr. Francis Lord's third volume of The Civil War Collectors Encyclopedia.
