From the MoHPC "The HP-41CX was the same as the HP-41CV but added the Time module (stopwatch plus clock with alarms), an Extended Functions / Extended Memory module, a text editor, and some additional functions"
What a dis-service they did...

If I remember well you can try:
[Shift] [catalog] [4]
If you get "DIR EMPTY" or file names then it's a HP-41CX.
If you get the same as function's catalog ([Shift][catalog][3]) then it's a HP-41C or CV.
