You left the best for last
If this is indeed a team bike built for Kelme for the 1988 season (and there is no reason to think otherwise) then.... just shattered my theory (actually two theories) of dating the EMC 1986 - 1989 frame.
...and very well - since they were wrong
At the same time he clarified some "anomalies" (as I thought so far) regarding the introduction of "teams" paint schemes in the A-series.
Sometimes it's good to turn the puzzle table over - especially if a picture of the Eiffel Tower emerges .... and on the box you have the Leaning Tower of Pisa....
Kelme was using 86/87 (red/white) paint scheme still in Vuelta a Galicia in August 1987 so our hero didn't appear until September 1987 at the earliest - so far I can't get used to the idea that maybe even later
So far I dated such a frame to the beginning (maybe March) 1987... this is enough for a whole comment
OK, I'm putting it together from the beginning - let's hope the Empire State Building doesn't appear
