This is an authentic Louis Vuitton soft-sided suitcase 70 cm wide. I believe it is called a Sirius bag. It is 27.6 inches wide, 19.3 inches high and 8.3 inches deep. It has SP0955 stamped on the inside--the only identification I can find. I can't find a model number. It has "Louis Vuitton Made in France" stamped on the inside and also on the little leather piece where you insert your name and address. Only "damage" is some wrinkling from sitting empty for years in the closet and some light scuffing to corner patches on bottom. Aso a tiny tear to the leather in one spot along the zipper (see final photo above).
I have filled it with bubble wrap to pad out the sides and flatten the wrinkles in the leather. Filling it with your clothing--the use it was made for--should do a better job. The inside has canvas pockets. This is authentic--not a knock-off. The inside is pristine. I am selling this for my brother. It was a gift from his first wife in 1990s; used once or twice but not used at all since 1999 divorce. Virtually no scuffing. Some wrinkles to sides from being stored empty in closet.
