Help identifying Montblanc Pen model numbers/type

[Jaguardoc504]

I am helping out a friend, who's husband recently pass, get rid of a pen collection she does not want.
There are a total of 4 Montblanc pens.
I am unsure of the model numbers, and am looking for a little help.
Please see the pictures below, and if you need any further information please let me know.
Right now i am just looking for information.







Any and all help is greatly appreciated.

The first pen is a Meisterstuck Rollerball 163
The next one is a Meisterstuck silver solitaire Barley ballpoint (should have a 925 hallmark)
The third pen is a Meisterstuck ballpoint 164
The last pen is a Burgundy Meisterstuck Legrand rollerball 162R

This is assuming that all of the pens are genuine.

I agree with what orfew says.

However, I wish there was a close up pic of the bands on that 164 BP. There is just something about it....
