Ithaca introduced their .410-bore at the same time, 1926, with the introduction of the NID. I think it was around 1926 when the ammo companies lengthened the .410-bore shell from the old 2-inch shell with 3/10 ounce of shot to a 2 1/2 inch shell with 3/8 ounce of shot.

With the introduction of the NID Ithaca quit cataloguing the 28-gauge, though they did continue to make some. Ithaca added the 28-gauge back to their catalogue offerings in 1932 when Western introduced their Super-X 28-gauge load in a 2 7/8 inch shell with 3/4 ounce of shot.
