That's an interesting bit of trivia, I am going to have to take a look as I
have not yet lubricated the speedo, My car is #222. It is still apart, It will
be interesting to figure the production date for this. Any tips on what I
should do to lubricate the speedo assembly before reassembly would be
appreciated.

Hey Gerardo:
The "black dot" Vs the "silver dot" that Kanto Seiki put on the Tach and the
Speedo for the 67.5 2000 and the 67.5 1600 happened at about the middle of the
production runs on both cars. I believe it was another late addition to the
DOT mandate regarding removal of all shiny surfaces in the cabin. The latest 2
liter car that I have seen so far without the black dot is Andrew Murphy's car
#00489. Take a look at the original gauge that you took out of the car and on
the back you will see a 5 digit "serial number." This number actually
corresponds to the date that the gauge and the car were made. I.E. serial
number 19047 would be for a car that was produced on the 19th of April 1967.
We haven't narrowed it down to the exact serial number transition yet, but we
know car #00489 came without the dot and we know that 6 days later they
started adding it. How many cars that were made in those 6 days we don't know,
but at least we can say with confidence that if you have a high serial number
car you should have the black dot and of course cars that are below #00489
should be silver.
It has taken us a couple of years and a couple dozen sets of instruments to
narrow this down and I would be very interested in hearing from anyone who
has a 2 liter car in the serial number range of #00490 through 00550 to see
just when they committed to the change. (I know, get a life.....but it is
pretty cool to put some some order to at least one area of these cars.)
