TL;DR
- Two-tone pin of metal construction, hand assembled and hand finished.
- Digitally re-created from original artifacts.
- Chrome polished highlights, with artifact-accurate level of subtle texturing for "gold" areas at front and edges.

- Collar-Style: Improved engineering from original artifacts with the inclusion of textured backing, two small placement pins (pin-style only), to augment original screw and nut system thus reducing accidental rotation of rank accoutrements when worn.
