I asked a friend for the body number of his 13 roadster. He replied F235959, mine is F236282, only 323 apart! My guess is probably made the same day.
There were 33,129 runabouts made in 1913 Model year, from October 1 1912 to September 30, 1913.
The average was about 91 cars per day. So Larry yours was made about three days after F235959, if Ford was only using Fisher runabout bodies.
This is a "Fisher"........
Back in my better days, I had a 1925 Pierce Arrow series 80 four door sedan. I loved that car. In the Nickel age Touring Club was a fellow that had a nearly identical (except for the colors) Pierce Arrow. They were two numbers apart.
(Larry, I saw your re-posting, but since Royce had put something here, I will bump this one back to the top>)
Drive carefully, and enjoy, W2
Now that's a heckuva way to go fishing!!
Now the question is what is his engine number compared to your engine number? In the 1911 production there is no rhyme or reason for the numbering. Sometimes a engine number will have a higher body number, sometimes lower. It seems as if Ford used a first-in last out inventory method for bodies in late 1911.
