She is in the 30-40 Krag caliber.
Now Cowboykell,

just remember, way back in the earlier to mid 1900's, whitlin wood was pretty much a standard item to do.

They may have gotten carried away with this one, but it is a good carving. I have a number of guns from my grandfather, that had his own personal customized fixes or touches to the guns he worked on and owned, so this kinda keeps in that personalized, make it your own gun concept. I also have guns that are original and untouched, other than me fondly handling them!
There has got to be some special story behind this carving of the stock. This picture does not show the very good detail of most of the carving.
I wish I could meet the person who did this one and get the story. The gentleman I purchased it from, says he got it in Colorado and according to him, this is somewhat a German folk style carving. Not saying that is true, just part of the story that is carried so far.
Cheers,
Oklahoma Dee
