Tony:
According to the TRA Concours manual, both master cylinders for the 4 & 4A
were cast aluminum and were left natural. A little past half way in the 4's
production run (CT25645) the cap was changed from a glossy black painted
steel version to a natural stamped aluminum. The change was made because of
corrosion between the dissimilar metals. I don't think that was a firm
change because I have seen more than one 4A with a glossy black painted
steel cap that was supposedly original. In TRA Concours, both types of cap
is allowed for the 4A.
