Ktos da rade wymyslic cos sensownego?
Myślałem, że będzie to trudniejsze, ale jakoś w miarę się udało. Przynajmniej tak sądzę...
Poniżej prezentuję dwa raporty ze Springsharpa, które powstały dla POW.
Pierwszy dotyczy prezentowanego na stronie 164 Świętego Jerzego. Natomiast pod nim jest jego wersja dopasowana (jak sądzę nawet nieźle) do budżetu zaproponowanego przez Oskara. Artylerię główną tworzą brytyjskie ośmiocalówki z Kentów. Jak stwierdziłem wcześniej, jest jej bliżej do okrętu syjamskiego, niż szwedzkiego. Ale taka jest cena za słabość ekonomiczną.
I jeszcze jedno. W słabszej wersji wytłuściłem zmiany wprowadzone przeze mnie.
