You have not yet asked a question, despite the question mark. The successor to the Forehand & Wadsworth Company, Forehand firearms were made from 1890 to 1902. Values are not high, but would depend on exact model and condition. Please note this is NOT a .38 Special, but a caliber .38 S&W.
I did my research on the gun itself and it is .32 caliber. Its worth about $1,750. for more info e-mail me at t7k7t7@aol.com
To distinguish between the .32 caliber and .38 caliber Iver Johnson revolvers, you can look at the markings on the barrel or frame, which typically indicate the caliber. Additionally, the size of the cylinder will differ; the .38 caliber revolver will have a larger cylinder to accommodate the larger cartridges. If you have access to the ammunition, comparing the cartridge sizes directly can also help identify the caliber.
Consult with a good gunsmith.
Anywhere from $10-$200, depending on condition, model, etc.
Forehand & Wadsworth changed their name to Forehand Arms Co. and was eventually taken over by Hopkins & Allen. Unfortunately without the serial number it is hard to narrow down an exact age. I can tell you it was produced between 1887 and 1915.
