Problem Solved. The Habaabi Khanjar.
Note to library.
The term Habaabi applies only
to a region in Saudia which was about 90 years ago in Yemen. Its main seaport is Jazan and was a minor hub trade linked to Muscat and Zanzibar. Habaabi is actually the regionals capital name and it can be searched on the web.
The Habaabi Khanjar in its original form can be seen at interesting jambiya on eBay
by Lew. It is noticeable in virtually all respects how similar this variant is to the Royal Khanjar of Oman from which it must have been copied. Transfer of style is estimated in the 1850 ad region. My theory about Habaabi tribal swathes of territory near Bahrain thus collapses though my primary theory applies.
