Today the ship people seem to think of when they think of Klingon ships are the Birds of Prey. The staple of the fleet though was the D-7's and the K'Tinga. As much as I like the K'Tinga there is something about the old smooth D-7 that speaks to me.
The model of the K'Tinga is really nice. A lot of it is solid metal with the engines being plastic. The stand holds the model in place but with all of the models in this series they are held in place, they are not screwed in or attached. The pro is there is no invasive way to hold it or loss of detail due to holes etc. The con is if bumped it can fall out of the stand. So keep that in mind with where you display it.
The actual ship comes in clkose to 350 meters long with close to 800 crew. They are a powerful ship. Some also have cloaking devices which can be unpleasant for their opponents. For its size the crew have few amenities and is a warship in every way.
Although the Vor'cha would replace the K'Tinga you will still find many in operational service. The first on screen appearance of this ship was The Motion Picture.
