The OP left a clue as to the format, "three of eight shots", tells me he was shooting a 6x9 camera. The number placement does indeed verify 120 roll film, and that the numbers had printed through. The last shot has some massive flair, but still a nice shot. A piece of black electricians tape over the red window will help some of this, especially on bright days. Enough light could be entering through the window to cause the imprint.
