Yeah I would think so. They only used lime back then, and it's the perfect thing for covering masonry. Portland cement ruined EVERYTHING.
I LOATHE portland cement. why did it ever take over? was it just cheaper or what? Sad to think lime mortar was used since the time of the ancient egyptians until about 1930...

I am pretty sure the baseboards were done while the plaster was still a bit wet. I assume it is easier as the plaster would squish down a bit that way but I'm not sure how long it took to plaster or what the drying time of it was. I assumed they did that to contend with any warpage of the baseboard lumber. if it wasn't dead straight , the plaster compensated a little or they hid any gaps in the skimcoating.
If I pull the baseboards there is plaster behind them but it is rough.
My baseboards are installed over lathe, but the plaster only goes down to where the baseboards are.
