Miss June has original, FACTORY installed seatbelts. This has been verified by Jim Breazeale at EASY and several others. These are easy to identify by the two parallel indents on each buckle and ALUMINUM hooks. Most of the 356 cars with seatbelts were either dealer installed, or installed even later.
Dealer installed seatbelts and seatbelts added later do not have this unique buckle. The original manufacturer of the seatbelts that were installed at the factory was Teka Automaten Gmbh. If you Google this manufacturer, you'll see they later invented the seatbelt reel mechanism.
The original 356 C seat belt anchors were plastic dipped. I was able to get some plastic dip made up in the exact same color and dip them again for a fresh look. Very happy with the result.
