There was one offered back in 1976. Was about 36" inches long. It occasionally surfaces, unassembled, on eBay. My assembled model (which is how I can precisely date it)unfortunately went to the trash heap decades ago, but it was well detailed and if you can find one, vintage, it is worth the money.
this is the only one i have have seen as of late, but it is kind of pricey. also floating around e-bay there are models of Maury floating around in the 1/600 scale that are pretty good, just make the changes to the ship, those are the only two things i can think of.
