One area that is so often overlooked in Sci-Fi series and Star Trek to a large degree is transport vessels. In Earlier Trek this was partly due to the fact that any vessel seen on screen had to be a physical model. That also lent into the movies and The Next Generation. So any new ship was a big deal that would eat into budget. If a new ship was to be shown there had to be a real reason for it. Transports are a very unsexy class of ship when compared to the ships of the line from any of the main races. For most stories they would be very important window dressing. At places like Star Bases, colony worlds, research stations and the like. In these places transports would be a key part of the supply chain. Far more than a ship of the line like Enterprise.
This is one of my favourite ships from Star Trek, It isn't pretty at all but it fulfills an important void. The Klingons would have a large transport fleet for resupply. It is warp capable but its speed and living conditions made it better suited for shorter runs, has a crew of around fifty and is a little more than fifty meters long. These kinds of Space Haulers are very needed in Trek.
The Model is quite nice in some areas and a little soft in others. Overall though it is good. The Stack like Structures and engine area are nicely done and the paintwork on this one is excellent. It has a unusual shade of green and a layer of grime and weathering. If you like unusual Trek ships this is a good one to get.
