Voigtlander Bessa II - how to open RF housing?

[codex0]

Hello all,

I recently found a delightfully underpriced Bessa II. I sent the camera out to be fixed up (RF optics cleaned, they're foggy), and shutter CLA'd. It came back worse than it left, so I did the shutter work myself (all speeds now work properly - yay! ).

I'm having some difficulty figuring out how the RF housing goes together - does anyone know how to get this open?

Many Voigtlander cameras have a small screw that's removed from inside the film chamber, usually in the "fresh film" chamber. However, I don't know this particular camera, so I can't say for sure.
