Did the addition of Gelatine in 1855 to the gum
affect either the colour of the gum or stamp
front or back?

Re: Addition of Gelatine
That is a good question. Just joined ,so late with any reply. What was the original gum?
Potato starch? Gelatine if pure is clear in solution. Becomes light yellow with slight impurities. It would only be guess work what effect it had on the colour of the gum and the face of the stamp.

have considered it relevant. Just wanted to know why.
