Diamond Edge No 5

I like to use hand planes some along with my power tools.  I've wrote about the other plane I tuned up that my wife bought at a antique store for me. Over the weekend I bought a new to me plane. It's a Diamond Edge No 5 plane. It is in good shape and just needs a little tuning and the blade sharpened. From some quick research the plane appears to be a WWII era plane.
