Yup... Sounds like it's this baby all right:
Seems this model was later extensively modified to become Kivas Fajo's private ship in "The Most Toys" (the engines at the rear are the telltale), and then redone several times until it became a Bajoran (Cardassian?) ship, the triangular one with triangular nacelles. One of the better reworkings, as the ship is nearly unidentifiable each time she gets a makeover.
