All of the original season 1 and 2 hero props were either designed and built by Wah Ming Chang or just built by Mr. Chang.
They were top notch hero versions, (moulded/vacu-formed plastic/fibreglas and machined metal parts ), but he was a non-union, outside third party prop maker and wasn't allowed ( banned ) to design and build anymore props or models ( after he built the Romuoan Bird of Prey model ) for Star Trek, after the start of the series!
There were two hero comms designed and made ( for the working, stopwatch moiré movement ) and two non-working, but hero looking versions made, by Mr. Chang, for a total of 4 comms.
All of the other comm variations, used on the series, were made/reproduced produced by the Desilu/Paramount art/props deparment.
Mr. Chang built two fully working, hand painted and detaioed small hand PHASER I models and 3 ( possibly 4, as a spare, for backup or parts , not certain of this fact ), fully working, detailed and hand painted hero PHASER II pistols ( one for each principal actor/character ), with, I believe, 6 hollow shell, machined parts, hand painted, mid-grade, non-functioning PHASER II pistols ( a few mid-grad, small hand PHASER I, as well ) and a few full sized prop moulded/vacu-formed, very thin shelled, quickly paihted, metallic sticker-ed detailed, very lightweight, “crap-looking”, far photograph, “extra cast” versions, built by the union Desilu/Paramount art/prop department at a very huried pace, when needed.
That is why the mid-grade PHASER 1 and II props have ONLY those detials that would b easily seen, up close,,by the cameras and some details of the hero version PHASERs, were not duplicated 100%, but created in a quicker manner.
Two or three hero, non-working, fully detialed static tricorder models were designed and built by Mr. Chang ( again, probably for each of the principal actors/characters and, probably one spare for backup or parts ) and that was it!
All other tricorders, produced during the run of the series, were ( including the “leatherette”/simulated leather/“pleather” wrapped ) built/moulded/machined by the studio union art/prop depatrment!
Star Trek produced these main series props ( as well as other custom designed and made props seen on the series ) on little to NO money/ budget!
A lot of these people had to work very late days ( sometimes into early mornings, of the next day ) to produce these shooting props needed for whatever episode they were shooting, when needed, and these artist/creators worked/built these, sometimes, not getting paid for any extra time they had to put in to create these complicated, futuristic-looking props, for the TV show production!
So, there was little to NO budget for the art/prop department, during the entire series creation/run, if later episode-specific props were needed!
So, it still boggles my mind that these new/needed, 3rd season hero version tricorders, were given the needed/neccessary time and money to produce two, possibly, three, brand new moulded, machine parted, fake leather textured wrapped a few, new “hero” use tricorders, for an uncertain 3rd season that was scheduled for a Friday, 10pm time “death” slot!
Here are some much better images of one of these “leatherette”/fake leather textured covered tricorders.
It is amazing the condition of this particular, screen used TV show tricorder prop is in after nearly 60 years has passed!
