Next few images have the MicroMachines USS Enterprise miniature thrown in for a helpful size marker. The Starline 2400 (3788 scale) series is the right size to fit with the MicroMachines mini. But the Starline 2500 series (3125 scale) makes a good heavy battle cruiser or dreadnought sized ship if you are after one.
Now get back to having a great Christmas holiday break!
