The British publication TV Sci-Fi Monthly, published in the mid-70's, was a rare item to find, and a great one. Here is an image and blueprint of the shuttlecraft from the inside cover of issue #3, which came out in 1976. The cover for this issue has already been posted, you may view it here, as well as more material from the same issue. Since this is such a short entry, I have added some extra bonus items below it.

Bonus: publicity photo of Celia Lovsky as T'Pau and Shatner from "Amok Time." Notice her hand on his shoulder!
Bonus #2: Covers from the first of the adaptations of the animated series scripts by Alan Dean Foster, which to me were awesome, having the scripts actually expanded upon (unlike the truncated versions by Blish), with only THREE half-hour episodes per book! I bought this one at the Chi-Chester's Drug Store on Vineville Ave in Macon, GA one Saturday in 1974 when I was staying with my grandmother, and read it the same day. Good times! The store is still there, by the way.
Extra special bonus! Below, we see some very revealing images of Uhura's panties during a scene from "Balance Of Terror." The flap on the back of the dress has come open, and she is showing more cheek than usual, even for her! What was Kirk saying, now? Who cares?
