Scotty's shirt is unique to the character and has been factory reproduced by Doctor Mego. The repro shirt fits a little more snug and is a little shorter. The collar is bigger, and the rank strips on the sleeves are a touch farther apart. The strips also have a slight texture, where the original has none. The shirt is marked DM on the inside near the collar.
Star Trek crew figures have a 2 layered emblem. It's a gray plastic type material with a silver foil on the top. The foil tends to fall off over time leaving the gray part of the original emblem. A complete emblem should have the silver foil. The emblem has produced by Emce Toys on their Kirk reproduction shirt. See the Kirk Accessory Check page for details. Scott's will be updated when Emce releases the figure with the emblem on a red shirt.
Trek crew pants have been factory reproduced by Doc Mego. The reproductions are a little bigger and longer than originals, but otherwise close to the originals. They are marked DM on the inside. They have also been reproduced by Emce Toys. The Emce repro's are almost exactly like the DM's, but the cuffs are a little wider, making the pants a little shorter than Docs and original Mego pants. The Emce pants are unmarked. Both repro's are made from a slightly slicker, more modern material than the originals.
The Trek weapons belt has been reproduced by Doc Mego and Emce Toys. Both repro's are identical and very difficult to spot. The reproductions have a very slightly more rounded look around the holsters, but even that is hard to see. Neither reproduction is marked.
The male crew members carry a blue phaser. They are cast in the same color blue as the communicator, but the blue (especially the phaser) tends to take on a greenish hue over time. The phaser has been factory reproduced by Emce Toys. The repro is a brighter blue, the lines on the smaller phaser attachment are a little wider on the repro, and the post near the back/top of the phaser sticks up a little higher. The main body of the repro is a little wider, and the handle is just a touch more narrow, which makes the repro not stay in the holster on the belt. The Emce is marked with the number 7 printed on one side of the handle. What can be confusing about this mark is the repro phaser has a 7 on the handle and the original does not, but the repro tricorder is unmarked while the original has a 7 printed on the backside. Bascially what that means is the 7 mark does not mean repro on all Trek items.
The male crew members carry a blue communicator as well as the phaser. They are cast in the same color blue as the phaser, but the blue (especially the phaser) tends to take on a greenish hue over time. The communicator has been factory reproduced by Emce Toys. The repro is a brighter blue, and it is an overall cleaner cast than the original. One of the telltales of the repro is a thin bit of flashing that outlines the unit. The repro is unmarked.
