Hi Jaf,
you replyed before I finish my message at end I recognize that mast is radio antena. But I also bring clear evidence of second periscope in Amethyste class "La Perle", last picture in your message also helps
You are right in saying that this conversation is useless and I am sorry you feel it is a dispute. I am just trying to give you information about the Amethyste class but I can easely understand that you have more urgent things to address to satisfy the DW community.
Never the less I thank you very much for your great work
Kindly accept my apologies,
Lau
