Calvary was based on the P2 Ogan. The Ogan is a capship however the model style looked better as a fighter/bomber.
Off the top of my head, the ghost, nighthawk, foxbat, falcon, galaxy, gothhek, pakriss, ra'toth, darkoth and majority of the capships aren't WC, although several are based on, or include parts of WC models. As for coming down the line: the unamed 3drt model, centaur, javalin, f-4phantom, liberator, sortahn, claymore (possibly going to be renamed), the f-7 model, ocelot, harpy, rave, super hornet, viper and majority of the capships aren't specifically WC models (some do feature wc model pieces or extensive modifications from existing models)
The bearcat got another minor tweak, just to the tables entries. More compatible with Sagas models although mine should be superior considering their a decade or so newer.
Also the black widow got a smaller model, check it out now.
Edit: Bloodfang now edited and smaller.
