I like Holt's but in this case it seems the specialist come to their limits. only because it come from the iberian peninsula dont make it a 14,5x41R spanish berdan double rifle.

anyway, they try to identify this good as possible. there are not many informations around about the 40 mm long Kugelpatronen( bullet cartridges or better rifle cartridges) based on shotgun shell like here a 24/40.
