If it is possible to scan the back of the stamp on a Black background,
that would help.
If you could take a scan of the back of the stamp on black background in "Watermark Fluid" That Would be even better.
warning only use "Supersafe Watermark Fluid" As other fluids may cause the ink to run.

The Watermark fluid will not affect the state of the gum.
