Unknown Vintage Pelikan

[berc]

Few days ago, I acquired an unknown vintage Pelikan fountain pen. Now I don't know much about it (I have had hard times identifying since it has only "PELIKAN" and "GERMANY" engraved on the cap), but I am sure it is not a part of the famous M series. Furthermore, I believe that is a vintage since I can not find it any new Pelikan catalog.
The nib is silver in color, and it has engraved "585" and "14C" on it, but it misses the pelikan logo engraved on it (also, I am not sure if the nib is made of gold, or just gilded). It has a black body and a silver cap. The pelikan logo is engraved on the top of the cap. I believe it is never used.
If it helps in identifying its age, with this fountain pen I acquired a ball pen as well (basically the same model) and the mine of the BP is a Pelikan 137 M. They came in a set, so I guess they should have been produced in the same period.
Any feedback and information would be very much appreciated.

looks like a pelikan 21 silvexa from the 1970's...

Agreed, a M21 Silvexa they produced it from 1973 on.

The cap is "strichmattiert", for me the main differentiator to the M20 Silvexa which was produced before.

 

And it's a part of the M family as it is a piston filler

A cartridge filler is part of the P family.

That's a beautiful Silvexa with a 14C gold nib. Nice pen. Enjoy it. They are good writers.
