This one was done at the request of BolianAdmiral over on TrekBBS and as the title suggests it is a TNG-era shuttlepod based on some concept sketches, done I'm told by Rick Sternbach during the run of TNG. As to why it was never used, you'll have to ask the man himself, however it's a good bet that it had to do with the expense of building a full scale mock-up. Either that or the show's inheritance of the ST:V mock-ups.
In developing the original sketches into these schematics I conjectured that it was an intermediary design between the boxy milk-float we know as the Type-15 and the Defiant's own Type-18 (I checked Ex-Astris and apparantly the Type-16 is a slightly scaled up Type-15.) Logically it could just have easily been an earlier design, with the '15 being a smaller more economic follow-up but my instinct told me that it looked more like a later, more capable design.
Axeman has already posted some 3D renders of the design in my BoBW Thread, also on TrekBBS, so feel free to check those out (I'm sure more are to come.)

Wow, the SS Heart of Gold and her shuttlepod Ford Perfect. So you think the E-D did have a shuttle Indiana Jones. Is there a Sam Freedle too?

That mock-up is a preliminary study model that Rick Sternbach made up out of cardboard and bondo. The shuttle was at first a concept to replace the small 1st season TNG shuttlepod, and then, was revisited as a short-lived concept for a shuttlecraft design for Voyager.
The image comes from a vidcap from the "Journey's End" VHS, which was basically celebrating the end of TNG. They were interviewing Rick Sternbach, and the model is sitting atop his filing cabinet, in his Paramount office. I believe that the full image is available on his website, for which there is a link at the Ex Astris Scientia site.
