Hi Bolek,
First of all, I am afraid we're facing a certain language barrier here.
Secondly, I beg your understanding concerning the fact that I cannot repeat all I have been posting on these topics for more than two years.
All I can tell you is that all the functional parts of a characteristic wheel-lock that you marked red actually never existed on this matchlock; there are no traces of the respective screw or rivet holes whatsoever.
May I recommend reading my former posts on both match and wheel-locks?
I hope this will add to a more profound understanding of the matter.
Best,
Michael
