The concept of model years was not like it has come to be since
the days of the Model T. The whole idea ran contrary to Henry's
automobile philosophy of building simple, reliable, easy-to-work
-on cars to change it up every year, just for the sake of changing
it up. However, Henry DID have a keen sense of business, and if
bringing "fashion" into the game sold more cars, ... or in this case,
helped Ford retain market share, then he was (reluctantly) willing
to go along. The Improved Models were Henry's first act of loosening
his traditionally iron fist from the reins of company marketing strategy,
but it would take through the Model A years for Ford to completely
embrace the idea of model year changes to generate sales interest,
and by extension, make older cars "fashionably obsolete before their
time.
As for the TT trucks, they were even farther behind the curve than
the cars, and more-or-less were the same, except for minor details,
from 1924 to the end. My TT was built with running changes, such
as a 25 dash and instrument cluster, but 26-27 pedals. Build date is
Jan 26, so it clearly landed within the 26 production run, but as stated
before, that had little meaning with Fords then. At was just a truck,
and because it was built on "this day" it got built with "these parts"
that just happened to be in the bins THAT DAY.
As they say in Chugwater, ... no pictures, .. it never happened. Let's
see this wreck of yours. Here is mine:
