Thanks for speedy answer.
If i like to depict the "first patrol" boat, i`ll need the top part of cutter and the SG without the bottom part of the cutter? Is it what Your sayin? Im sure one eliminates another as they occupy same spot. Right? What bar You talking about- i can hardly see the U-boat.
Is it the vertical thingy running down through the SG? Is it possible the cutter was fixed with SG?
