FED 5 top plate removal

[efinglada]

Hi FSU RF experts,

I want to remove the top plate of a Fed 5 to clean the viewfinder and rangefinder windows/prism and my question is if the lightmeter dial has to be removed, seems to be fixed by a spanner nut, but it is quite hard and I am afraid to break it

Also I have removed the 3 screws that hold the nameplate but it will not come off

I cannot find information on how to procceed specifically about the FED 5

Any help will be appreciated

Eduardo
