Help dating dress

Hello, I have inherited a collection of vintage dresses. I plan to keep them as Im very interested in them. I would really like some help with dating these items. First up is a golden brown dress, probably rayon. It is marked with a CC41 rationing label so clearly this narrows it down to about 1941-51 but can it be narrowed down further? thankyou. Douglas

 

Would you happen to have a picture of the label?

 

yes, here are the labels. View attachment 154110 View attachment 154111 ACH]
