Stanley Bench Plane With No Visible Number

I have sold a large number of Stanley planes and everyone had a number on it's base. This plane I have has the name STANLEY on the base at the front, but no number anywhere on the base. The tote has a a sticker on it that shows the word STANLEY and with 4 red squares. I'd be very grateful if someone can tell what I have. It measures 11" long 2" wide.
