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.
In business 1871 to 1902. Value range 25-100 USD
Forehand Arms was the successor company to Forehand & Wadsworth. They were in operation from 1890 to 1902. Not aware of any serial number database for them. Sorry.
