Kennedy carbines are rare birds. That is a good looking one as these go, they all seem to have all led hard lives. It's probably worth every bit of 2000 euro, maybe more. If you want to shoot it, ammo is easy to make from 45-70 cases. Technically, the rims are a little thinner on 45-60s, but my Withney Kennedy rifle has no problem with the thicker rims. If the bore is a little rough, it will probably like heavier bullets, in the 405 to 430 grain range. The action is stronger than a Winchester 76, but not as strong as an 86.
