Professional Treasure-seekers?

[Raynor]

Suppose that these "treasure-seekers", as the Dwarves call them, are actually the Rangers, the remnants of the Dunadain---of course their true nature remaining secret and skewed by the Dwarves' own penchant for seeing only the greed in others?

Hm, that would have to mean that their information about these seekers was very distorted, seeing the difference in height (the hobbits were half the size of the original numenoreans, and even if the dunedain dimminnished in that respect, they still were taller than normal) and in life style (hobbits being a sedentary race at that time).
