your samples up to this point have been archives, this thread would've got more attention in the "Game Archive" section i think.
anyway the new bld sample looks like a stream of zlib compressed chunks with 0x800(?) padding but the file ends abruptly for some reason.
i don't know anything about this game's models, you'll have to contact the owner of that wiki for the conversion scripts.
this bms script will decompress those zlib streams in your new bld sample
