Beautiful receiver!
the Opus was Tele's TOTL receiver.
I am noticing from the pics that you are missing the ferrite AM antenna. This is quite common since it's simply glued to the rotating device.
It also appears to have been modded to accept standard RCA plugs, probably for the tape/pick-up input.
Does this unit have FM (UKW)? I don't see the shielded front end with the ECC85 on it.
