I have several 2 I can identify with water marks but these two I am having a problem with.In my opinion the first one appears to be a forgery? not sure about the second one though.

Watermark fluid, or even Shellite from the hardware store, evaporates and doesn't affect the gum. I use it all the time (ventilated room, no naked flames of course!!)
I have got Shellite I use it to get Self adhesive stamps off paper I use to use acetone to check for watermarks, lost my bottle through evaporation.
I will give Shellite a go and see if I can get a result.

Omg, you guys are freaking me out! I never heard of Shellite so i googled. Wiki says “Shellite also known as Tridite is an explosive mixture of picric acid and dinitrophenol or picric acid and hexanitrodiphenylamine in a ratio of 70/30.” yikes!

Shellite in Australia is essentially lighter fuel for gas stoves and lights. You can buy it at supermarkets. Tridite (also called Shellite) is a different substance altogether. Aren't common names wonderful.
