Unknown mechanism

[Giogrlj]

A friend of mine just gave me an old pocket watch. The case is in very bad condition but the movement itself seems to be in a quite good shape. I can't identify which movement is this, since I have to find a missing winding stem. I attach few photos in a case somebody would be able to give some hints. 

Thank's folks

The movement is FHF, something like this. But it will not help much to find stem.  Sometimes making one is easier

I thought is FHF. Sounds good to make winding stem by myself but I am not in watchmaking on this level.

The problem is that this movements were not produced with the modern level of standartization, there for parts from one didn't fit well to another, even if they may look the same. May be it doesn't concern the winding stems, but yet there are not spare parts for such movements in supply companies, not even clear calibre identification possible. And where calibre identification  is possible, there are no Ronda numbers for the balance staff or the winding stem for this calibers in the data bases.

One of the problems when looking for spare parts of course is identifying the watch you're looking for spare parts for. But there's the other problem what makes you think that whoever made this watch actually had spare parts available for the watchmaker?
