A powder horn ... unusual ?

[fernando]

Do you usually see this version, guys ?
It will be Portuguese but i have never seen one with two opposite horn ends with equal spouts. I don't think one of them is for shot as they both have the same (powder) mechanisms. One for priming and the other for load ? And how does the shooter knows which is which; i see no differentiation marks .
Better pictures when i get it back from a watchmaker friend whom i am trying to convince to reproduce one spout spring that is missing. Otherwise everything in good order.
Opinions appreciated .
