Just documenting this plane. It will fill this slot in my bench plane family until I get crazy lucky and find a 605 1/4 in the wild or have extra money to plunk down on the LN version of the plane. I am upgrading from a post WW2 version of the plane.
This one is an early example and it is corrugated. If you take Patrick Leech at his word this is the scarcest (5 1/4 corrugated plane) of the Stanley bench planes. Unfortunately this one has been drilled to hang on the wall.
More info can be found on Stanley Bench Planes at Patrick's Blood and Gore.
From the original eBay Listing. (Note to plane sellers, if you are selling a quality plane this is a good way to photograph it. If your selling a junky one, carry on with the out of focus photos taken from strange angles.)
