any evidence about it that it should be that gun? (the .50 I mean)
I'm sorry but I do not understand what you said ?

In all cases, for Alkmaar's Dutch, it seems that they do not have a single gun model ...
- some embarks any gun (but may carry a 12.7 MG in emergency).
- some boarded a 12.7 MG.
- others seem to carry a heavier 20mm (possibly a French mount ?)
Use of older 20mm oerlikon were almost impossible, a too older gun mount....
