Recently I have been looking for Schneider Gold Dot Dagor and located two lens in my area.
I found two lens, but the coating does not look the same.
One is a lot warmer (magenta-purple at outer glass, and blue-greenish
at center), and the other one is cooler (green at outer glass, and
purple at center)
I have such a lens. If the the lens has a MC on the front rim and is in a Compur 3 shutter, it's multi-coated late production with a reflection of deep blue. The other one is with Copal 3, single-coated and has a color of amber.
