I have what I believe is a numbered marching 13 with a early 80s restoration. It runs I've drove it "Fires Right up" magnetic doesn't work or its been removed. If I keep.it I will put an alternator and breaks on it.
Anybody know what's it's worth and how rare is the the 13 with all the brass in place?
A picture is required to determine its authenticity.
You might say no Model T is "rare", what with over fifteen million made. Of course that's relative, the "brass" cars numbered "only" a million and a quarter or so by 1916. Then there is the question of "survival" . . . there were around 170,000 cars built for the year model 1913, most of them touring cars.
Value is a question of authenticity and condition. As Ed says, show us some pictures, you'll get some educated fair estimates here.
