This may or may not be the original model and case. It is from the website of an auction house. The description is below.
"This magnificent scale model is of the SS Bismarck, later christened the RMS Majestic II, a member of the celebrated White Star Line and the largest ship in the world in its day. Astonishing in size, construction and intricacy, this model beautifully exhibits everything that made this great ship a modern marvel. Crafted to 1:48 scale, every exterior detail of this historic vessel is explored and recreated with impeccable accuracy, from the rigging attached to the three smoke stacks, the benches, railing and lifeboats on the wooden deck, to the perfectly spaced portholes, anchors and propellers on the brightly painted hull. A model of this size and complexity would have almost certainly been crafted to commemorate the construction of the actual ship.
This model is in spectacular condition and exhibits a level of craftsmanship that is unsurpassed.

At 956 feet long, the Bismarck, or Majestic II, was, like its fleet sister Titanic, one of the most impressive ships ever to cross the oceans. First launched in 1914 and intended to be the German imperial touring ship after the expected German victory in World War I, the Bismarck was still incomplete after the war. After Germany lost the Great War, the ship was handed over to the British as compensation for the loss of the RMS Britannic hospital ship, and served instead as the flagship of Britain's White Star Line from 1922 until 1934, becoming the second fastest passenger ship in the world after the Mauretania. The re-named Majestic II proved her swiftness with an average Atlantic crossing speed of 24.75 knots. That same year, the ship carried 2,625 passengers, the highest ever carried on a White Star ship."

"Ship models: from useful tool to coveted collectors items" by Theodore W. Scull
"In New York, handsome steamship models once graced companies' midtown offices along Fifth Avenue and in the area of lower Broadway. Climbing the steps of Cunard Line's massive headquarters at 25 Broadway, one was greeted by flanking models of the Majestic on the left and the four-funneled Mauretania, painted white with green boot-topping, on the right; and then within the Great Hall, the Queen Mary held a dominant position to the left, with the Queen Elizabeth to the right."

"There was a wonderful 16-foot-long model of the Majestic, later given to the South Street Seaport Museum. Stolen one night, it was never recovered. A similar model is now at the Science Museum at Toronto."
