Master Tracking List

Alpha Delta Epsilon Zeta All ten Star Trek TOS communicator props, with details - HeroComm.com

Wah Ming Chang was paid for providing ten black-bodied communicator props; two working "heroes" and eight static "dummies."  Here they are in detail, as best as can be tracked during the three seasons of Star Trek as well as after.  The Greek naming is our means to provide a uniform scientifically-oriented nomenclature.  In determining their order and to keep them in sensible groupings, we took into consideration their prominence and importance (heroes first), familiarity, current status and moiré pattern.

In case you're wondering how we figure out which comm is which...

Once a comm is found and analyzed, we will offer a "Details" page with complete data on that one prop.  Look for it in the left title bar.

 

Alpha
(hero)

The Details

The most salivated-over and desired comm, owing to its gorgeous star turns in "Friday's Child" and "Patterns of Force," Alpha is the version from which nearly all replicas are based.  When we think "communicator," we mostly think of this one.  Now that it has been found and fully documented here, we are seeing a whole new slew of ever-more inspired Alpha copies.

Beta
(hero)

Familiar mostly through its only close-up in "Day of the Dove," this lesser-known of the two heroes differs more from its famous sister than most people realize - most prominently with a similar but modified "spider" moiré configuration mounted lower in the control well and an antenna that opens up not more than 45 degrees past vertical (less than any other comm).

Gamma
(dummy)

Made famous by Stephen Whitfield Poe's book "The Making of Star Trek," this beautiful prop, perhaps the most quintessential of all the dummies, had a rare close-up for a non-hero, in "Assignment: Earth."  It was one of the most frequently-utilized comms, with appearances in far too many episodes to be fully listed here.  Besides having its antenna wire likely made of steel instead of the usual brass, it has one unique feature in that the antenna is mounted further forward than the others, closing down just outside of the control well instead of over the control panel.  The center Light Siam jewel was also glued on crooked.

Delta
(dummy)

The Details

A true workhorse, this comm was used all over the place.  It famously fell to the ground in "This Side of Paradise," where the antenna bounced open from a rubber band wrapped around the wire near the hinge wheels.  Those wheels curiously have a groove cut partially around their midlines - from source unknown.  Delta is easy to ID in screen caps because of its wide moiré bezel and the empty screw holes on the bottom.  It was originally owned by Set Decorator John Dwyer and then sold through a 2001 Profiles in History auction.

Current status:  owned by Paul Allen, currently on display at the Science Fiction Museum in Seattle, WA

(dummy)

The Details

Control knobs placed very far apart, a pushed-in upper left edge of the moiré pattern, and a large dark distinct tarnish blotch on the antenna are the key id features when finding this often-used comm in screen caps.  This piece, also originally owned by John Dwyer who first sold it to Mark English, had those traits removed during a refurbishment by the now-current owner.  It has an antenna wire made of steel rather than brass, like with Gamma.

Zeta
(dummy)

The Details

We only see this comm twice in three years; once as disassembled on a barrel in "Patterns of Force" and next again sitting motionless on a table in the famous "Spock's Brain" group shot.  Its antenna hinge today has very restricted motion, and if this problem has been present in some fashion all along, it would explain why it was never used in action on the show.  The current owner took it apart again and has the Velcro and the mic grill stored separately.

Eta
(dummy)

For some unknown reason, this seemingly normal prop got almost no camera time, so many of the details are sketchy.  A few of the external tells are a full flip-back antenna with screws, the antenna has flattened sides along with some distinct mild tarnish blotches plus a prominent solder spot 1/3 of the way back on the left, and it shows some generous midplate exposure also on the left.  Inside, the moiré pattern might likely be a logarithmic spiral inset into a bezel ring mounted extremely low in the well like Theta's.  The center jewel is probably a hyacinth like so many, but the left and right rhinestone colors are a bit of a guess.

Theta
(dummy)

While it is distinguished as being the only comm without a red center jewel, some of the internal features are not well known for lack of good close-ups.  It has the sharpest "boxy" bends on the antenna's four sides and a very low-positioned moiré ring.  Screen caps hint at moiré pattern "bunching" lines (fully consistent with the same wavy pattern as in Delta and Iota) but much lighter, suggesting the same image but a different source; plus the dark contrast seen in one scene tells of clear plastic top layer.  This is probably the only dummy to have a two-layer moiré pattern!  A smear of excess squeezed-out glue is atop the moiré around the lower inside of the ring lip.

Iota
(dummy)

Seen often early in the series, it got relegated later to the back of the line.  We got lucky, though, with a couple shots that show the moiré well enough to figure out the pattern from the "bunching" of the waves that form their own fuzzy lines.  It is the only one of three comms that ever had its antenna swing all the way to the back that also had no screws (though its hinge stop-pin was replaced and fell out a few times).  This occasional feature combined with an angled cut along its Velcro's high-up rear edge makes it easy to spot from just about any angle.

Kappa
(dummy)

This comm got the best close-up of any dummy, in "The Omega Glory."  It too was a workhorse, seen aplenty all throughout.  It also has the most unique (and easiest to see from a distance) moiré pattern, a static printing of the "spider" Pattern #4 clipped from a catalog ad, plus some distinctive antenna solder marks.  The center jewel looks to be not a faceted flatback but a 3mm diameter round ruby or garnet cabochon gem with a "bullette" shape, probably harvested from a wristwatch crown like those Wah also used on his two tricorders).  This communicator's bold look and frequent appearances are why we have it bringing up the rear of the list.
