Interesting.
Appears to be Safety automatic Standard Model w/external hammer, double-post latching system.
First Model with single-post latching system was made 1894-1895. So your handgun must be either a Second or Third Model Safety Automatic (No safety; definitely not automatic).
Doesn't have the owl cartouche on the grips. Grips are wooden, not gutta-percha.
Is the revolver single-action or double action? (Most likely double-action, but let's check.)
Iver Johnson handguns were used in three prominent assassinations/shootings: William McKiniley, Theodore Roosevelt, Robert Kennedy. Kennedy was killed by Sirhan Sirhan's Iver Johnson .22LR.
Iver Johnson handguns originally sold for around $6. I'll give you $10 right now, w/no complaints about profiteering.
