Good luck with the revisiting and discovery process!
Here's how I think of the Trumper issue. There is what the company calls the "Trumper Collection" -- which contains four scents from the later Victorian era (1876-1882). Each of them is masculine-styled, but each has a distinct character. These are Wellington (lemon-mint), Marlborough (cloves & cedar), Astor (caraway & sandalwood), and Curzon (an herbal chypre).
Eucris is from a slightly later date (1912) and is somewhat similar to Astor or Marlborough. In my experience it is a bigger, more powerful scent, arguably more complex.
In order of preference, I own Curzon, Astor and Eucris.
PS -- on my skin, I haven't detected a leather note in any of those. Perhaps a slight musty note in Wellington, but that is part of its particular charm. "Dusty lemon drops in a library."
