Thanks for posting the Model N Runabout photo. It appears to have the later body irons for the buggy rail and top to attach. That would make it a 1907-1908 style. The earlier Model N bodies were a little smaller but the later ones were apparently the same as the Model S Runabout and the body was used on both the N Runabout and S Runabout when they were producing both models.
For additional information on the early Model N Runabout vs the Later Model N Runabout and S Runabout body irons, please see: http://www.mtfca.com/discus/messages/179374/218818.html?1308709936
Note it also appears the step plate is probably broken off. At a straight on angle it is hard to see but that is looking slightly down on it and we should see the rectangular step plate. We do see the rest of the bracket and support rod.
And a favor to ask: If you (or anyone else) ever post a 1906-1908 Model N, R, S, or SR photo and I don’t at least say “thanks for posting” please send me a note. I am always trying to gather more information on those cars. Thanks!
