I am not the creator of these models. I only modified them a little bit for Celestia. The original creator is Astra/Snowfall.
Additional thanks to LukeCEL for helping convert the cmod files to binary (this was done to reduce the file size).

Note: If these models are to be used for a tidally locked minor moon, then MeridianAngle/RotationOffset must be set to 180 to get the orientation right.
