Moskva-5: Fixing frame window pin

My camera lacks one pin that I need to open a frame window for 6x9 but it has one for 6x6 which I can't use, so I've decided to move it.

Hello how are you thank you for an amazing video. I am just starting getting into a analogue cameras and photography and as a present for start I did received moskva 5 model camera and I do have few problems with it already. I haven't tried with film yet but for some reasons the speed wheel does not move when i am trying to rotate do you know what might be the problem and how to fix it? another thing is that There is no ( that thing ) when u putting your film than u stretching that film into that plastic thing ( sry i dont know what is that thing called) so i dont have that one maybe do you know where i could get one possibly? also interesting is that i do not have mask as well but my model has just two red windows not like yours has three.

Дим, я не совсем понял, зачем предыдущий владелец сделал третье окошко, а потом его и заклеил куском ракорда. Зачем?
Существуют ли фильтры на этот объектив или проще поставить И-23 с резьбой?

Интересно, для какого кадра третье красное окошко на крышке фотокамеры. Ведь красных круглых окон должно быть два а не три???
