Doors – How to remove this door knob on the mortise lockset

doorslock

I have an old mortise lockset that I want to replace. And I already removed all the visible screws and the cylinder. However, I am not able to figure out how to remove the knobs. I could loosen the cover a little bit and I saw a "half" screw head on one of the knob. Posting some pictures here as well.

There should be a catch release hidden on the underside of the inner knob. Push in, hold, pull knob out with your 3rd hand.

If you don't care about the knobs you can be lazy and just cut/bend/crush the escutcheon plate to get to the screws.
