I have an old original picture of a 1915 touring from back in the 1920's showing the car with an accesory cowl vent.
Never seen another one until seeing this car on eBay that is advertised as being a "1915".

I see a bunch of mismatched connecting rods.
My 23 touring came with one. It does help some with the heat in the summer!

Royce -- I'm glad you put the "1915" in quotes. As I'm sure you noticed, there are few parts in the chassis which are '15. Looks like a decent driver, but not worth anywhere the asking price due to the lack of unique '15 parts. Even the authentic '15 cowl would have a large hole in it for the ventilator.
Looking at the pictures I see metal caps on the front seat cushion arms and a steel firewall? Maybe a late 1922 body? The engine cast in January 1914 is not from a '15, but not worthless either.
Of course it could be a clumsily restored '15. Maybe someone added those items? You almost have to see it in person to know for sure. Anyway it is a good solid useable Model T that someone will enjoy.
I see a wood firewall with a hood former. Can't tell about the cushion caps. Also a later transmission cover and a starter. There appears to be solenoid on the firewall next to the steering column too. The battery cables look like they run to the back seat--Unsheathed and running through sheet metal. Wonder how long that lasts before erupting into a big ball of flames.
I'm no expert on brass era T's but shouldn't a 1915 be equipped with an aceylene lighting system? Jim Patrick
1915 was the first year for magneto powered headlights. There may have been early '15 production with gas headlights.
There are factory Ford pictures showing cars equipped as such, which are thought to be prototypes, but since everybody who was there is now dead, we can't really say for sure if there were regular production like the pictures.
