Bulldog,   Welcome to our little group.  I have access to only the serial numbers listed in the late Frank Mallory's book, but there are others here who will have some additional sources they can check.  i imagine you will soon be hearing from them, too.

in the meantime, Mallory does not list your specific number, but all of the numbers he does list both before and after yours are listed as 1896 Carbines.  That in itself is not conclusive that yours, too, is a carbine rather than a modified rifle, but it is a really good sign.  We use your photos to identify those parts that are specifically for carbines or for rifles to develop a little history of your piece.  That's a lot of the fun in collecting these and other antiques - trying to guess where they've been and what they've done.  Again, welcome to you.
