Rollei Magic II, How to remove middle lens element ?

Gauthier Prontormat S 602K

Leaf shutter as used in the Rollei Magic II 6x6 TLR.

Front of the Shutter.

So I want to remove the Middle Lens element.
Only problem nothing will budge using normal force :bang:

Should I turn the outer lens tube (see green arrow) ?
Or
Should I turn the lens ring which has 1 pinhole (see red arrow) ?

Hope somebody has experience with this.

Well, yesterday evening, after giving this problem some more thoughts, I answered my own question after coming up with a solution involving an adapted rubber door stopper and a 1mm drill which fits into the pinhole. Worked like a charm because the rubber gives some extra grip and prevents the drill from scratching up the lens.

That's a very clever solution. I probably would have drilled another hole opposite the original so I could use a spanner, but your approach is more elegant.
