Star Trek: The Search for Spock (1984) "Master Chief Petty Officer 2nd Class" Rank Pin

This "Master Chief Petty Officer 2nd Class" rank pin was custom made for use on various Trek films (ST2 to ST7). It is made of resin and would have been worn by extras during filming. It is worn on the left sleeve and on the right shoulder. Probably not seen on-screen, but definitely used in the production, as provenance is impeccable. Shoud any reader find a screencap with an extra wearing it, I would be very grateful. [SU]

Star Trek III: The Search for Spock (1984) Star Trek IV: The Voyage Home (1986) Vulcan Priest costume

Despite triumphing over the evil Khan, Admiral Kirk's victory is a hollow one -- McCoy (DeForest Kelley) is going insane, and Spock (Leonard Nimoy) is dead. Or is he? Kirk (William Shatner) jeopardizes his career by commandeering the U.S.S. Enterprise for a mission to the Genesis Planet. If he and his aging crew can defeat a deadly crew of Klingons, they may just be able to rescue their absent friend.

Costume design by Robert Fletcher.

This costume was custom made for the production and worn by an extra. The costume consists of a long-sleeved, full-length, blue-gray robe with a raised collar and loose, pleated, sleeves; an over the shoulder, black, silk-like sash featuring a beautiful copper-colored dragon motif. A wide, reflective gold stripe over the shoulder, a smaller red stripe on the left, and red faux jewel featuring a Vulcan iconographic symbol in the center. Included is a rust-colored, Vulcan-style hat featuring accent trim in metallic-gold and brown stripe or ‘brick’ pattern, chinstrap, second accent strap that drapes across the chest and red faux jewel with similar symbol. A sewn in Paramount tag reads "7-4" and a label reading "Evens Riccardi" is almost covering the tag. This costume may have also been reused in various Trek television shows. [SU]

The hat can also be seen in the early scenes on Vulcan of Star Trek IV: The Voyage Home  (1986), where some priests are working in the background, with costumes similar (probably reused) to those from Star Trek III: The Search for Spock.

In one scene, the costume seems to be complete, as can be seen in the screen capture below.

In the next scenes, however, this seems to be part of two costumes, instead of one. In the movie, male pristes use the embroidered sash and the red hat, whereas the female priests use a white costume. Based on the collar, it seems that this from a female priest garment.

Male priest. As you can see, a dark red and gold sash, with red hat.

Female priest. White dress with the very distinctive collar.

And this is the scene in Star Trek IV: The Voyage Home.
