Removing the top plate of Zenit E / B

[alan44]

Hello, have just joined as I cannot find information elsewhere on removing the top plate of a Zenit B or E. (Tom Tiger's pages on Zenit E disassembly seem to be unavailable now.) I am hoping to clean the ground glass screen as it has become rather dull with specks (and lumps) of dirt visible. My main problem is how to remove the winder shutter release mechanism from the right hand side.
Many thanks, Alan.

You need to grip the chromed ring around the release button with something soft. I use a jar opener, and for more stubborn rings, a small slip joint plier, with latex tubing over the jaws. The ring (and the threaded parts below) are left hand threaded. The "Learn Camera Repair" website has service manual
