Non-typical Secondary mirror on 20" RC?

We recently discovered that the secondary mirror of our 20" RC has a hole that runs through the center. On the side of the secondary facing the primary there is a metal tube (for lack of a better description) that projects towards the primary (see pictures). My colleagues and I have not encountered this configuration before. We discovered this issue when attempting to collimate the telescope with a Takahashi scope, which has obviously not been ...
