What era/size are you looking for? No promises, but I want to say that all postwar Schwinns used the same headtube length between mens and ladies bikes. You'd have to go back prewar to get the longer length, in which case, you won't find the blade style. I could be wrong; though, I'm nearly positive that by the middleweight era, they were the same and I believe earlier yet.
Are you looking to make a King Size fork by chance?
