Hi erichsande, thanks for that but no, it's not the case here. I read these posts carefully and unfortunately problem lies elsewhere. That arm looks as it should and is not engaged either.

that's interesting indeed Dennis. If that was a ten minute fix then I'm presuming everything was easily accessible via the bottom cover. Perhaps I will need to remove some other parts to get deeper to that gear in the film advance mechanism. Is this correct please?

that's correct, no film inside the camera.

Does it mean that removing the top cover is not enough to find the reason please? Do you know where inside exactly?

I have just acquired Nikon FM2n in a nice condition. It has one problem though and I'm looking for some advice please. Basically the film advance lever is stuck and won't move. However when I use the multi-expousere tab/switch it's then possible to cock the shutter and release it. Then again, film advance lever is stuck. I removed the bottom cover but everything looks ok there and I read that the mechanism there is responsible for cocking the shutter only rather than advancing the film. Cocking the shutter is basically possible when used with ME tab, releasing as well. My thinking is that the problem lies somewhere else, possibly under the top cover? Would anyone be in a good position to help please, has anyone experienced such an issue before?
