gorgeous patina on this pair of captains rank in sterling by BB&B.
Very fine quality Bailey Banks & Biddle made Sterling captain’s rank insignia each with a gorgeous untouched rich dark bluish patina. False embroidered bars.
Pin back with locking ring, not commonly seen in WWI but very shortly after. No doubt these are WWI and early in pattern, but upgraded after the war. This pattern is rarely seen after the 20s.
Just the best.
