Here are two more library finds. As noted on the pictures, the dates are approximately 1915 and 1925, in Theresa, Wisconsin.
Both pictures are 1917 or later. The top one is obviously misdated. The bottom one shows a 1917 - 22 Model T.
That second picture is interesting. It is not a TT, but a greatly lengthened car chassis with a pickup type delivery box on the back. The rear fenders are simply the regular T rear fenders probably bolted onto the boards of the box. It also has the front fenders of a 1915/16. The radiator and hood may have been changed to make the car look newer.
The first photo also has a T converted into a truck, however it has a more common conversion kit such as a Smith Form-a-Truck. It is also a bit earlier T, appearing to be about 1913.
The rest of the cars are all 1917 or later. Given the apparent condition of the first non-truck in the lineup as well as the only car with fenders on it, I would guess it was a year or two old (or maybe just very dirty). The windshields are straight and all appear to have cowl lamps. Probably 1918 or '19.
Great photos! Thank you for sharing them.
Drive carefully, and enjoy, W2
