You're buying the homemade Paperweight and Key Ring shown in the photos,

These items were carefully crafted from an earlier vintage (likely type 9-10 (02-02 patent) ) Stanley #5 C plane that was damaged beyond salvage.

 

Still visible on the top of the paperweight is the remnants of the rear handle base casting. Also of note is the three "owner mark" slashes on both heel and toe.

It didn't seem right to split them up so they are being sold as a pair.
