There is absolutely none of those products available where I live so it was good old elbow grease and WD40 which makes me nauseous.
I cut back the spine by an inch and sprayed WD40 into the spine and around it and left it for a day. I placed the plate in the vice place without clamping and the spine resting on the vice top. Gave it a few mild taps on the plate with my Thorex and it separated. Success! but I didn’t have the courage to separate the two.I scrubbed with 120 sandpaper and more WD40 , there is alot of pitting but worth continuing.
I transferred over the hole diameters and heel edge profile and cut with a hand grinder over a number of passes. There was no heat generated. Drilled out the holes gave the handle a very quick sanding and reassembled.
The tooth profile on the plate is unusual as below – large valley, peak, small valley peak, large valley geometry which is repeated.
Two swipes of a saw file per tooth and a cut test on pine. It works but not perfectly yet. It seems less aggressive than my Veritas 14tpi tennon saw.
Thank you for all your help, I am curious about the saw tooth pattern though.
