As someone who has historically paid much closer attention to TNG/VOY props, I’m continuing my little self-education program on TOS props, and have lately turning to some of McCoy’s tools. I love the little spray healer that appeared in TMOST and, as I recall, the Starfleet Technical Manual.
@robot418 has suggested that perhaps it was a found item: a woman’s purse perfume atomizer. Something like this:
That certainly seems plausible to me. My own guess would be that it was inspired by a real object like that but then machined solid just so that it could be made repeatably. (The one in TMOST doesn’t appear to have a hole at the tip, for example.)
And that, thanks to @Buddahaid’s recent photos, that SDStudios made at least one version (at right below):
What else is known about this item? Anybody know any TOS episodes I could look to for screencaps? Any and all guidance would be appreciated.
