Y'know... I really don't care what anyone else says about this freighter, to me, it makes sense. Low warp, massive transportability. One ship carrying a lot more material than almost anything else, just doesn't get there too fast. That's the thing that I liked about ModelsPlease's freighter, which is why I wanted to do a TOS version of it. Used Lord Schtupp's TOS Ptolemy freighter (which gives the ship a shuttlebay) as the basis for my additions, and I think it turned out pretty well. If noone else likes it, well, too bad.
Putting it up for download at Battleclinic, and here's a shot of it just before I redid the registries and a couple of minor textures. Enjoy, or not. Either way, it exists and is up for download.
(edit: and here's the download link)
