Ikoflex Favorit shutter repair

[brombromp]

I have this Zeiss Ikoflex Favorit with a shutter that needs to be serviced/lubricated so I need to access it.
So far I have managed to unscrew the front element of the taking lens,
but then I don't know how to proceed, there are no visible screws, retaining rings or whatever...
Any hint?
Thanks in advance

I haven’t opened on of those before, but on many other TLRs the front face needs to be taken off to reveal the shutter. I would guess that there will be some screws underneath the leatherette. If you are careful with removing the leatherette, you can reglue it back after you’ve finished. Maybe you’ll also have to unscrew the viewing lens.

Me either, Nathan, but a quick look at the images suggests you're probably right.
