Hmm... I'd still argue that the torpedo tubes indicated by the model are all pointing forward from the pylon junctures, as per the reuse of Constitution
-refit neck elements, and that this ship lacks aft torpedo tubes since there aren't suitable surface features for them. Or if there's an aft tube or a pair of them, it would go between the impulse engines where there are some greeblies on the desktop model and a greebled cover plate for the motion control arm in the photographic model.
Also, the warp core should probably have a central reaction chamber thingamabob, as portrayed in "Peak Performance", rather than a featureless straight shaft. Okay, so the Hathaway
might have had a reactor refit, as many of her consoles also looked more modern than those of the Stargazer
. But in that case, the reactor in this MSD might be made more "TMP'ish" still.
