Interesting reading about the different cases. My father recently passed away and I found one of those cig cases among his assorted memorabilia. He never mentioned it to me so I really don't know anything about it, I do know he stopped buying this type of stuff in the early 1950's so I feel comfortable saying it was acquired well before then.
The case has the Mercedes-Benz logo on it (3 star) but its just the word Mercedes (no Benz) which I believe to be correct for that time frame, benz merged around the early to mid twenties if I'm not mistaken.
