I did that a long time ago;, cannot recall where the fastening elements were  that I removed in order to shorten the whole thing, probably hidden by the bayonet with what the Germans call a "madenschraube" on its side.

What i vividly remember that I did wrong was to discard the little black conical shield fastened to the bayonet assembly. It was acting as a baffle to guard against stray light from the light twice crossing its interior. This catadioptic is known to produce a brighter picture center (sort of reverse vignetting), but without this bafflle it was even worse
