Yes Iver Johnson did make 410 shot guns, I own 2 break open 410 shot guns both made by Iver Johnson.
Iver Johnson did not have a 410 gauge or bore in 1907. The 410 came along about 1920.
The rough value of an Iver Johnson 410 shotgun serial number 001 is about $300. However, this will depend on the condition of the shotgun.

The Iver Johnson Hercules grade hammerless shotgun in 410 gauge was made from 1924-1935 by Iver Johnson.With the serial number that you possess I would assume that it was made early on during production.
Yes they did make them, around 1930. I own two Iver Johnson SS shotguns with raised ribs, a 410 & a 12ga.
The Iver Johnson "Champion" is the most common version, although there are older models. Would need more information to make a valid identification. Assuming good shape, about $100.
.410 shotgun shell either 3inch or 2 and one half inch
