Hi, Hood. I give up trying to made the net with dots, and with a solid color looks much better:
And as a gunboat
Unfortunatelly I was unable to find the exact model of MG in rifle (7.65x53) cartridge used by the Navy (could be a Hotchkiss with strip feed, which was my choice for the drawings, or less probable, a ZB with top magazine) in 1941.
Cheers and thanks.
