I don't know if anyone wants to follow up on this, but I found an antique auction site at   (You need to Login that has a few old firearms.  In April they are auctioning a Krag model 1896 that say is a carbine. Serial number 80489.  22" barrel.  They estimate it will go for $800 to $1000. I am attempting to attach a photo from their website. If you go to the site you can see a higher resolution photo.
