Interesting "dotting" you have on this FL! Never seen in that way before.

My dots are sort if yellow colored, so bright bronce or brass.
Looks like, I just removed the old dirt. Have to polish them when I receive the "Flitz" and try to take care of the tail piece.
(I see, my Elan had less love in the past, what it definately deserves. It's on me now...)
