Is there any real difference between the “.58 Berdan musket” and the “14,5 berdan espagnol”?
The same between the “11*53R Comblain belgian” and the “11mm chilean comblain” and the “11mm brazilian comblain”?

This may help explain the differances between the various cartridges used in Comblain Rifles:


Note the Belgian Comblain was 11x50R not 11x53R.

Is somebody else can give an answer?
