Atlas 8-40C phase I and II

[Stan]

I noticed that Atlas list two different undec. versions of the 8-40C, phase I and II.
What is the difference in phase I and II?
Which version is what I see under the NS flag occasionally.

Just curious, making plans for a future project. Maybe Santa will be generous.
