This is a rare Stanley Bedrock No. 605 Type 6 Jack Plane with dual patent dates. It was manufactured in the United States and is an antique original. The brand is Stanley and it is a carpentry and woodworking tool. The bottom and sides have been flat lapped to perfection and edges relieved.  Iron is sharp and straight. Rosewood is about as good as it gets with no chips or cracks. A great user that has no problem doing paper thin shavings.
