I also have some interesting pictures of my Ford radiator cosine emblem restoration being fired in the furnace and buffed before chroming.  Haywood Enamels of Australia did the work for me at $175.00 per emblem.  I have several and they are beautiful!  The 28 emblem has a lip around the edge and is different than the 29 and 30, which are the
same.  Of course the 31 is unique also.

Each component was restored to original without any detail left off.  All
the metal including shocks, etc. came on this particular car, not parts from
another car.  Matching motor and frame number.  I am the second titled owner
of the car.  It had 26,000 original miles on it when I purchased it several
years ago in 2002.  The wood framing was replaced during the restoration.
The motor does have a counterbalanced crank and adjustable valves, which is
an update for these type restorations and an update flat tube radiator
instead of the round tube radiator, which was prone to overheating.  The car
was built in August of 28.  In November of 28, Ford started putting a single
disk clutch in his Fords, since the multi-disk clutch with a very heavy
flywheel was installed in the earlier Ford cars had some design problems.  I
used the November type of single disk clutch and a lightened flywheel in my
car, since I did not want to have any problems with the multi-disk clutch
latter on and have to change it out.  I have just changed the car over to
the new cast iron brake drums that pass the judging standards and also make
the car safer on the road.  It was restored with the original steel brake
drums, since the car only had 26,000 miles on it and they were not worn, but
the original Henry Ford steel brake drums commonly fade when riding the
brake in the mountainous areas of the country.
