Buffalo Horn handled Tourist.
Great looking knife, did they make many models with those scales?
They did. According to a catalog from the 1950s or 1960s several 74mm, 75mm, 84mm and 91mm models were available with horn scales.
Here's a Spartan-like model (91mm so off topic in this thread

I also have a Victoria branded knife with a single clip point blade and horn scales coming my way
