This elbow rest is of brass or bronze. Each of the three ends terminates with a well-cast yali-type head, with mouth agape.
The stem unscrews from the curved top section to reveal a thin, pointy, double-edged blade.
Such devices were intended to be used as arm or elbow rests for sitting or mediating sufi mendicants, although the structure might also have been used as a muscat rest for firing. The concealed blade also allowed the mendicants to protect themselves.
A related, though cruder, example is illustrated in Aryan (2005, p. 154).
The example here has a golden patina and obvious age.
