This is a very old 9.5 inch knife and is clearly stamped “1865 Wm Rogers Mfg Co.” and “warranted 12 DWT”.  The pattern is 1907 Dunster. 

The “1865 Wm Rogers Mfg Co” stamp is a trademark used since 1865.

This piece is obviously old and worn, but I understand that collectors have their personal ways of cleaning and how they want the piece to look.  Therefore, I did not clean or polish it. 

This piece came from a deceased relative’s collection.
