Legato’s battle footage I’m referring to is not what was ultimately shown. He was told to film the battle as if it was already in progress (i.e. that most of the ships were already destroyed at the start of the scene rather than the intact ships starting the battle as was eventually shown.) Legato apparently scrounged around for old models from BoBW and other assorted wreckage to use. He definitely reused the Nebula Melbourne and most likely used the Kyushu, as it was seen docked at the DS9 model for a test shot. Greg Jein also mentioned that his two BoBW models were taken from his personal stock, whether for this shot or for some other purpose is unknown. Legato mentioned that he made sure that the wreckage had the same names of the ships mentioned in BoBW, namely the Tolstoy, the Kyushu and the Melbourne. Since both the Melbourne and the Kyushu models were still available, that left only the Tolstoy, which never had a model associated with the name. So Legato presumably added the name to a piece of random wreckage, but what that wreckage was is a mystery. I’m sure the AoST book got their info confused. Those study models are not in BoBW. As a matter of fact, there is only one ship or piece of wreckage that hasn’t been identified fully, and I’m 90% sure it’s from a TMP Klingon Battlecruiser model kit.
