Thank you!
Were the upper deck gangways used to load the mines?
I don't know for sure but I bet that's exactly how it was done.
Very Dubious for the 1940-1941 ship-version to carry aft (near the aft-mast), a single 37mm/69 M1942 or LM42 model (in service by mid-1942 -1943)
Good catch; the 37mm gun has been replaced with a correct version.
