Salaams all .. No the configuration is Omani Kattara with an odd / different pommel arrangement. Just looking around my collection of a few dozen such weapons (straight and curved) none of the pommels are standard..some in a knuckle bolt end style others tubular ended and some without a pommel. Others with a pommel hole but some without.
Tippu Tib is quite likely to have had the design added from his African travels and this perhaps shows the potential influence onto Omani Kattara particularly from Manding designs.
