i strictly collect traditional o gauge and would like to model an F-1 berkshire of the original Norfolk Southern
the F-1s were the lightest berkshires ever built and served the original NS from 1940-to 1950 when they were sold to the N de M and later scrapped
i'm thinking of using a 726 but would like to hear more options first
also was the boiler grey on some numbers as it looks such on some numbers
the original NS had 5 berkshires 600-604
another task is capturing the whistle these had - a throaty steamboat whistle that could chill the spine
i'd give anything to hear that whistle i tell you
