Hello Folks. Mortuary swords are on my radar at present because I don't have one and I am torn between the odd and the exemplary. I have a Cavalier rapier (with a Toledo blade - remember Jim) that has a very similar hilt to the Mortuary but I have my eye on two examples of Proto style Mortuaries. The one has an unusual shell, the other a thumb ring, which is what I am leaning towards. It has the Green Man rather than the Cavalier head and I suspect will have been hilted on Islay which according to a reliable source is where many Mortuary swords were hilted.
ps
Your example Triari would have made my choice even harder.
