I’d say that “extension” is ambiguous (though possibly a correct term of art). Cotton = massive source of fibers. As far as I know, these are some type of shim devices to manage how far the mount ring sticks out. If the connector was still attached via its screws to the mount ring, they may have lifted the lens by the rear housing and, in a mear moment, the lens fell apart and the weight of the lense broke the wire and the flat flex. 8^), McMaster-Carr calls them extension springs, so that’s as good an authoritative source as exists!

This would aid repair if you are able to source/make just the flex circuit and reuse the connector. There are mechanical zoom stops (the two slotted screws) that are nice and robust, and again, good weather sealing between each outer barrel. The rear view of the assembly shows just the backplate and the four screws holding it together. This barrel fits between the inner barrel and the lens assembly and helps translate the rotation of the zoom ring into linear motion of the inner lens. Things. The Nikon does this mechanically. The baffle is felt-lined, whether for absorbing light or dust, or both, we don’t know.
