At the present time the scanner portion of my printer/faxer/copier/scanner is not working, so I can't scan in that 1939 review of the Remington crimp.
Generally the only one of the "short shells" to be made for some time after WW-II was the 2 9/16" 16-gauge shells, which lasted up to the early 1960s. Probably because of all those 2 9/16 inch chambered Browning A5s.
The 8th and 9th Editions of the
Western Ammunition Handbook, while undated, show the post-War style Super-X and Xpert boxes and still offer 2 5/8 inch 12-gauge, 2 9/16 inch 16-gauge and 2 1/2 inch 20- and 28-gauge Xpert Shells. I don't have a 10th edition, but by the 11th Edition,
Western Ammunition Handbook, April 1947, the only short Xpert or Super-X shells offered were 2 9/16 inch 16-gauges.
In the early 1920s, in both 1 1/4 ounce 12-gauge and 1 ounce 20-gauge, the "modern" progressive burning powder shotgun shells were introduced in 2 3/4 inch cases. When the 16-gauge 1 1/8 ounce load was added the next year it was put up in the old 2 9/16 inch case. When Remington Arms Co., Inc. introduced their 5-shot Model 11 and 3-shot The Sportsman autoloaders in 16-gauge in 1931, they were chambered for 2 3/4 inch shells, and Remington brought out a special shell the Auto-Express in a 2 3/4 inch case, still with 1 1/8 ounce of shot, but with a quarter dram equiv. more progressive burning powder.

When Winchester/Western added this 2 3/4 inch load to their 16-gauge Super-Speed/Super-X offerings about 1938, they list it a a Mag!! Not to be confused with the 16-gauge 2 3/4 inch Magnum shell with 1 1/4 ounces of shot which came out in 1955, along with the 1 1/2 ounce 12-gauge and 1 1/8 ounce 20-gauge 2 3/4 inch Magnums.
