The 44 Colt is a centerfire cartridge and is not the same cartridge that the Henry took. The Henry and later Winchester 1866, sometimes called the "Improved Henry" were chambered for the 44 Henry Flat (44 rimfire) round. The 44 Colt is very similar to the 44 Remington which is encountered very often in the model 1875 Remington Army revolver.

There were some pistols chambered in the 44 RF but they are not often encountered. Here is a Smith and Wesson single action American in the rimfire caliber. It would have interchanged with Henry or '66 Winchester cartridges. This particular specimen was manufactured in 1872, IIRC.
