Here is a link with some information,

As Jimbobborg stated the 1873 was not made in 38-55, the Model 1894 was and is a very desirable rifle in good condition.
Winchester did make some Model 94 commemoratives in 38-55, the Legendary Frontiersman for one, I have one and it's a great rifle in that caliber, here is a link to information on the 38-55, as with most rounds that originally were loaded with black powder the factory loads are mild but it can be loaded pretty stout for modern rifles.
