My new 1930s Suitcase?

I just bought this at a thrift shop in Tucson, Arizona so there's no background on it. It's leather bound, and 21 inches long, 18 inches tall, and 8 inches wide. I joined this group hoping I mind find an expert who can tell me the age.

I'm a retired historian from the Arizona Historical Society, so I did some research. The baggage tags are from the Cunard White Star line and the Mauretania, which you can see written on the tag, was launched in 1938.

At first I thought it was a replica because White Star had another Mauretania lunched in 1906, a sister ship to the Titanic. But the 1938 ship was launched just after the two companies merged. They liked to keep re-assigning the names because they stood for quality.

I go to the beach every summer and thought it would be fun to get an old suitcase and paste copies of 1930s California travel posters reduced to sticker sized. I'm still going to do that, but this was a perfect find for that purpose.

I welcome any input on the brand, age, and origins of the case. It's pretty stained as you can see from the picture, so I'm not worried about ruining the value by putting replica stickers on it. I'm going to use it for it's original purpose, and enjoy it on my vacations for years to come.
