Thank you all for the great info and responses.  I am sure that is way more than I had learned on my own.  I was not sure about the carbine vs cutdown question as the serial number seemed early but the sights had certainly changed.  The bore looked very clean and "factory" looking so it must have been done by somebody who knew what they were doing. 

This gun came from Michigan as well and was used for many years hunting there.  I have a box of ammo for it and will give it a try soon.  Was out at the range last night with a stainless 1911 national match from the same collection and a muzzle loader I was checking for zero.  Fun times. 

Here are some more pictures of the krag.
