Iver Johnson manufactured the Champion line of single barrel shotguns in a variety of gauges as well as .44 and .45 caliber with 26 to 32" barrels, external hammers, and automatic ejectors, blue with a walnut stock, between 1909 and 1956.
Many early shotguns were single shot muzzleloaders. Some were double-barrel with barrels arranged side-by-side. This is also true of later breach-loading shotguns. The action style for these single and double-barrel breachloaders is 'break-open'.
Yes they did make them, around 1930. I own two Iver Johnson SS shotguns with raised ribs, a 410 & a 12ga.

Wards sold single shot and double barrel IJ shotguns under the tradename of Hercules.
No they did not. Cooey only made single shot shotguns starting in 1948. For awhile, back in the late 30's, they assembled shotguns for Iver Johnson in Canada.
What information would you want? Crescent made single shotguns from 1893 to 1930. If it has a large side hammer and damascus barrels, it would almost certainly be from before 1915. If it has fluid steel barrels and a center hammer (or is hammerless) then sometime after 1903.
