Shutter release loose, Compur 1

[Jerevan]

The small threaded piece where one inserts the cable release ... is loose on my Compur 1.

Does anyone know if it is held by a small nut on the inside (repairable) or if it is riveted (get another shutter)?

Nothing is riveted.

This sounds akin to the famous "there is no spoon" ... but as I understand you, there is a nut in there.
