Here's a photo of
Helen Gilbert that does look like a bit like the girl on the trolley with the pigtails:
Helen Gilbert is someone who impressed me very favorably with a performance that she gave in
Andy Hardy Gets Spring Fever (1941). Yeah, I know, how could anyone tell if any acting was going on in a picture with that one man showboat,
Mickey Rooney? Well, she did it by being very quiet and stole (or was awarded?) a few scenes with the boy dynamo, who falls in love with her character, an "older woman", a teacher at Carver High. You might want to check this movie out when it is broadcast on Dec 26, 10:30AM on TCM, (it is only on vhs).

Helen is the serious girl on the left with her hand on Andy's shoulder. I wonder which MGM producer she told to take a flying leap, leading her to date and even marry a bum like Johnny Stompanato while her career dwindled down to appearances as "Uncredited Girl on Trolley". My! They weren't teaching those girls in the MGM stable good taste in men, were they?
I don't know if that is the girl you are looking for, but it might be. Good luck, Nancy.
