Major Warren’s authority does not rest on an identification badge. The film builds it through visible signs and stories that the people around him accept, dispute, or use against him.
There is no verified record of this badge
The sources consulted do not make it possible to identify a specific military badge whose display would confirm Warren’s cavalry rank. It would not be appropriate to invent an inscription, an ID number, a manufacturer, or a scene in which the object is presented. The fact that the character wears military-looking clothing does not prove that he carries the item described in the question.
The papers tied to the bounties, the letter attributed to Lincoln, and the signs of the uniform must also be distinguished. Each serves a different function. The documents about the fugitives support an economic activity; the letter alters a relationship of trust; the clothing refers to a past and to a way of presenting oneself. Grouping all of this under the idea of a badge erases those differences.
Rank has to be recognized by others
Marquis Warren presents himself as a former Union cavalry officer. The word major is part of his public name and his reputation. However, that status does not oblige every character to grant him the same respect. Racism and wartime loyalties shape the way military authority is received.
The film shows that a visible sign does not work automatically. A uniform may evoke experience for one interlocutor and hostility for another. The same garment enters different relationships depending on who is looking at it. That is why reducing Warren’s credibility to an object that supposedly proves everything would run counter to the problem the story develops.
Mannix knows stories about the major and uses them to challenge him. Ruth has an earlier memory and a present impression. Neither simply examines a badge and accepts its result. Identity is negotiated through memory, speech, conduct, and force, within a society where those resources are not distributed equally.
Props do not replace a verifiable biography
The costume can be analyzed as part of the character’s presentation without turning him into a historical military record. Warren is a fictional figure, and his clothing belongs to a film production. Similarities to period uniforms do not make it possible to reconstruct a real career or assign documentary authenticity to every accessory.
The precise answer to the question is to recognize that limit. There is not enough basis for a record of the supposed badge, but there is a basis for observing how the character needs others to recognize his rank. The film turns that need into a conflict: Warren retains an authority he must defend again and again, even when his appearance seems to announce it before he speaks.
