I have compared the mystery car photo to a 1905 Pope Hartford and there are too many dissimilar features in my opinion. The hood and radiator on the mystery car are slightly rounded on the top with curved corners, the rear fenders are curved and the rear doors have smooth sides without a horizontal line across the door. The 1905 Pope Hartford has a sharper peak to the hood and radiator, the rear fenders are flat and there is a horizontal line across the middle of the rear doors following the body lines. The Pope also has a "box" in front of the rear fenders for possibly a step plate or chain guard. See the link for a photo of a 1905 Pope Hartford, Model D 20 hp. The photo in the link looks a lot like the photo Dwight posted above. http://www.classiccarweekly.net/2015/10/26/1904-pope-hartford/
