The HP 41C series has three models, here in chronological order:
The HP 41CV is basically the same as the HP 41C but with 5 times the memory (319 registers, almost 2 kB). I suspect the V in HP 41CV might be there to indicate that number 5.
This model of the series (and the HP 41CX as well) has golden lines around the keyboard. The original HP 41C has silver lines.
There is, by the way, a fully operational HP 41CV on desk at work. I still use it. I
usually leave it in such a way that when I press the ALPHA key the first three letters of my
girlfriend’s name are shown using the "C", the small
"a" and the "≤". The latter looks just like a lower-case
"t" (shift SIN in ALPHA mode).
This particular HP 41CV has the 82104A card reader extension with makes the calculator look even better, the one on display here with the card reader is the one on my desk. The HP 41C series design is already stunning. Beautiful lines and a really nice wedge form. Usually attaching stuff to calculators spoils their form, but the card reader attached to my HP 41CV fits so perfectly, it actually amplifies its aesthetics.
