Right you are; this one’s a PVM-8043MD. Looks like it lacks the 16:9 mode, manual degauss and tally light. I believe MD signifies “medical”; removed the cover and there is some shielding around the deflection yoke.

Thank you for mentioning that model number. That page has some good troubleshooting info relevant to the white balance problem I’m seeing with this one. Will post something nice if I can fix it!
