I realize that this message was old, but hoping that you are still reading. My great uncle Johnnie Walker was in that film. My dad used to tell me about it when I was a child. It was one of the movies that he remembered and also Third Alarm, since John Walker played a fireman and his brother Bill was one. It ran in the family. I remember finding a copy in California, but they said I could go there to watch it. It is in their vaults.
If anyone has any info, I would greatly appreciate it.
