I keep thinking back to the film Some Like It Hot. That was the one with Marilyn Monroe as part of an all-female brass band?
I don't think a non-vocalist all female group would have been very likely given the sexism of the 50s and early 60s. About the only way it would have been possible would have been as a novelty act, and the probably target market would have been men.
An all-female, instrument playing, song writing group that appealed to young women would not, I think, have been accepted into the record industry before the late 60s at the very earliest.
