Like Papamambo, I remember this ship from the old West End Games Star Wars RPG, when it only existed as an entry and some simple "front and side" line art. I never much cared for the "humpback" look (and this thing is supposed to be maneuverable ?), but I have to say the CCG art made the concept a bit more palatable. I'd be curious to see a model.
It's the sort of ship that is also kind of attractive from an RPG point of view, in that it COULD be flown with just one person, but it can also carry passengers. (Wookieepedia entry lists it as having a crew of 1-3 PLUS 3 passengers.)
Visually, it has the bonus of sharing aesthetic elements with the TIE series of craft (so "obviously" an Imperial fit) yet not a typical "TIE bulb + different wings" sort of variant. Functionally, it's a very different role (support!) than most TIE designs.
I'm wondering whether I might be able to manage a kitbash, given that the wings are so flat (i.e., good contenders for plasticard). Given the canon length of 24m (meaning a model about 3.5" long), it would seem that this isn't the sort of thing where you'd just use a TIE Advanced for a base. (I suppose at 3.5" long, a Titanium model of Darth Vader's TIE Fighter might produce a cockpit bulb and main body that's about the right length for a starting point, but there's no way I'd want to try sawing through die-cast metal to replace the wings with plasticard.)
