Wow, I found one of those once, not nearly as complete as yours...From what I gather an incredibly rare bike. You could try looking for any markings on the top tube where tank brackets might have been if there was one. Mine dated to 1936 and the frame looked identical to yours from what I can see. If your fenders are aluminum, they are incredibly rare as well as the light and rack. Really cool bike, what a great find! How much did you have to shell out for her?
