Unidentified knife

[Sjkn4kds]

I recently purchased this pocket knife but haven’t been able to determine its manufacturer or age. It does have a tang stamp but much of the lettering is worn away. What I can see appears to read “CHAR”. Can anyone help me to identify and/or date this knife? I have found out that Imperial made knives for Ruchards but can’t find any information on that brand. I’d appreciate any suggestions you would have!

There was a Richards in Southbridge, MA 1862-1908. (Houston Price's "GUIDE"). J.O'.

Welcome here.

Are there any stampings on the back side of the tang?

Thanks! No markings on the back side of the tang.
