You might need a combination of tools. The Smith's Detection ATR FTIRs are great, but you would probably crush a portion of the stamp.

The work that's being done is impressive so far.
Like
"the plates wore out too fast because the pigment was rust"
Xref says..... no iron present. And by the way brown, red brown and dark brown are chemically identical.....
I wouldn't mind seeing that sort of thing applied to maybe brown/black Lenox, or Blue Old mill.
I can make some guesses about the paper composition, but things were weird back around 1910. Lots of technology changes both in papers and inks.
