Finished up the rank striping. From left to right, we have Admiral, Commodore, Captain, Commander, Lieutenant Commander, Lieutenant, Lieutenant Junior Grade, and Ensign.
Admiral is, of course, conjectural, since we never see an Admiral's ranks stripes in TOS. To my knowledge, Lieutenant Junior Grade was only featured in "The Naked Time" and was the supposed rank of Joe Tormolen.
Correction: According to this article at Memory Alpha
, Admiral Fitzpatrick's rank insignia was, in fact, visible. Although I couldn't find evidence of this in "The Trouble With Tribbles", there is the "You're in Good Hand with Tribbles" outtake which shows Fitzpatrick has the same rank stripes as a Commodore. For my purposes, I'll leave that middle stripe on the Admiral to differentiate between the two.
The outtake I'm referring to can be seen below 0:28 seconds in...
[EDIT] Check out the corrected Admiral's stripes below!
