Yep, that was me. Soaking wet card wrapped in paper and clamped in a vise for a couple weeks.
I wasn't expecting water to do anything. The inks are oil based so water really shouldn't have any effect whatsoever.
I'll eventually escalate to alcohol, then an oil based solvent. One of those should produce a result.
And if Alcohol works it means the inks were based on a non-petroleum oil like linseed oil or shellac. And those sometimes won't truly harden in over a century. See the stamp card proof that left an offset over a century after printing that I posted.
Pressure and vibration may do it, but I don't have the ability to test that. I could maybe build a machine, but that's got a bit of expense and effort. If someone wants to fund it I'd be open to discussing it.
I'd still like to see more specific info on which factories were printing what. It would be interesting as its own information.
