If Schwinn Made Firearms?

[IMR-4320]

Any Iver Johnsen experts here? I've got a beat up 5 shot top break revolver, chambered for .38 S&W. Mostly interested in figuring out when it was made. I understand that these go back to the late 1800s and some early models were best suited for black powder rounds (not like I ever intend to shoot this thing, given that the cylinder has a few degrees of free play when it's cocked and, well, Iver Johnsen). It has but one patent date on the butt (apparently this revolver was used for cracking nuts and driving nails when not in its intended use) and shows a good bit of wear from being drawn from a holster or maybe a lady's burlap undergarments. Any expert information, crude comments, or random musings are welcome.

That's an Iver Johnson third model large frame safety automatic hammer revolver.

The 4 pins in the frame and the owl on the grips looking away from the cylinder make it a 3rd model.
3rd models have the double post latch and are smokeless powder rated.
Your no-letter-prefix 3rd model was made between 1909 to 1919.

There is a book by Bill Goforth which could get you the specific year from your serial number, but it's a $120 book which is more than your revolver is worth.

Awesomeness. Thank you. I probably won't use this for concealed carry, but it's nice to know its age and basic details.
