About this 3D model

First three stages of the Soviet's N1 Moon Rocket, as individual stages. I used the interstage to link them together - no explosive bolts or anything. Working on the actual spacecraft now - the booster's relatively easy :-) The stages are 1/1000 scale - basically I saved meters as millimeters. All dimensions are exact, and when possible I modeled the fourth N1 rocket - each model was a bit different, most noticably the plumbing shrouds.
