Before and after. The emblem is a bit battered after 60 years and someone repainting it twice (and damaging some of the plating). The new paint was easier to use but is different than ones I used in the past. I could do better on a second try, but this is good enough. This is one of 4 I've seen (even on the I-net), none on a car and the second in original colors.
The bumpy finish is normal for this emblem. The gold plated aluminum is cast bumpy, much like the FIAT emblems. I think these were applied only to Neckars of '61 to '64 to replace the similar shaped FIAT logo insert on the hood ornament. Few Italian FIATS were imported; those built by Neckar would have the oval Neckar emblem or the NSU-FIAT logo, making this fairly rare.
