The introduction of the JMB designed Remington Autoloading Shotgun in the 1905-06 Remington Arms Co. catalog showed only two barrel lengths, 28-inch plain barrel on the No. 1 "Standard" Grade to No. 6 "Premier" Grade and 20-inch for the No. 0 "Riot" Grade. By the 1906 catalogs the option of a 26-inch barrel was added to the No. 1 to 6. Those remained the lengths through the last The Remington Arms Union Metallic Cartridge Co., Inc. catalog in 1920. The first Remington Arms Co., Inc. catalog in late 1920 includes 30-inch barrels for the Model 11, but both the pump guns the Models 10 and 17 were offered with 26-, 28-, 30- & 32-inch barrels.
The big 1923 Remington Arms Co., Inc. again only offers 26- and 28-inch barrels for the Model 11 and includes the following --
"Our experiments show the Remington Autoloading Shotgun, fitted with the standard 28-inch full choke barrel shoots just as hard and just as close as any other type of shotgun. WE DO NOT FURNISH A LONGER BARREL THAN THIS."

The
Remington Shotguns pocket catalog, circa 1925, also only offers 26- and 28-inch barrels for the Model 11.
The 1929 Remington Arms Co. Inc. catalog that introduces the Model 11 with the new cross-bolt safety lists barrels in 26-, 28-, 30- & 32-inch.

By the 1938 catalogs they give all the different barrel options --

but by then they don't show 32-inch barrels for the 16- and 20-gauges.
