According to the information here, this scale model HIND took 8-10000 hours to build and is accurate down to the rivet separation. Apparently these guys made a business out of making models for clients. Man, I was doing that in my basement when I was a kid making some pretty cool stuff (I've won prizes I might add, I have cred!) and I never thought that people would buy 'em.
Regardless, it's a damn nice model :)
