I've obviously had this for a long time, in actual fact I had two, one from the Space Crusade game and one from the Space Crusade supplement, which means I also got the thre Tarantual Sentry Guns and another Chaos Dreadnought with four weapons points, more on that later.
As you can see at the time I wasn't happy with the little fella's mouth, so some Milliput sculpting came into play and I bored out the Bolters!
But I have plans for this baby now. I've never liked the way the sarcophagus, because of it's snap fit construction, just ends flat. So what I hope to do is use some bits from the venerable dreadnought, and the quad autocannons from the Aegis Defence Line and make my own Mortis Dreadnought, y'know the Dark Angel and successors only dreadnought that Dark Angels can't have [because it's not in the Codex] and every other Codex can! So if I take something like the bits below I can cut just behind the head on the Space Crusade sarcophagus, 'hinge' the cowling on theVenerable sarcophagus and find a way to fit it in. Then the autocannons will fit perfectly in the sponsons without any extra work, unlike if I was trying to fit them on a normal dread...
Anyway, it's another 'long-term' project as the pieces still have to be bought...
