Cool pic Jake, but in speaking with my mom and expanding the car pic...it was not a medallion, but Darrin flags where the normal medallions would have been. Again, when he bought it from his fellow Army bud whose father owned the dealership in 1956; I'm going to have to agree with the previous post...aftermarket add on from the dealership or simply customized. The flags do look nice. Searching through pics and parts to see if I can come up with them to see if they some how were custom create Darrin flags...
Regarding the mirrors: sadly they are no longer on the car to confirm, but they do nicely match my '55 Victoria, so probably fomoco...did kaiser have their own side view mirrors? Or were Darrins just customized with other brands?
