Finally back to the shop . . .
I've seen a number of yellow coils, but the correct black case to yellow plastic transition (paint) line is not clear to me.
On the left in this pic is a repop which I think has the correct line demarcation. None of the yellow 'plastic' portion is painted.
On the right is an original coil, but the plastic or yellow portion of the coil has been painted above the metal band by a restorer.
Is either paint scheme correct, from a concours perspective?
As an aside the original coil says "Dist." with the period included. As does "BAT."
The repop say "DISI" and "BAT" with no period. Odd that such an easy mistake to spot made it through into production.
