Salaams All~ The Al Ain Museum has a great collection of antiquities (and a particularly extensive and excellent section dedicated to archeology of the region... brilliantly carried out by the French Team)
In the weaponry section a display of "various types of swords"...and there amongst the different types is an Omani Battle Sword (Sayf Yamaani, 3rd from top) in this case adorned with 2 silver buttons at the cross guard and a silvered pommel. From memory I think it has a dot at the tip...last time I stood in front of that case was 1988.
The line up looks like Kattara, Quaddara, Sayf Yamaani, and some sort of Flysa.
Captured for posterity ... below.
