That looks a lot like Lord Schtupp's Monitor. The Monitor has different nacelles, a normal bridge section, and a gold deflector, but the engineering hull is very similar to the model in the OP, but with more details. It would be easy as pie to swap out the nacelles, and it wouldn't be too hard to give it a blue deflector. The weird rectangular bridge module would be a bit more difficult, but if you're not too in love with that detail, you'd have it made.
