I have been corrected, as there was no catalogue, which I said there was, it is a book with the items mentioned, and in BL the Oriental Reading Rooms are the pictures referred to in the text - sorry

.
However, in Elgood's book The Arms and Armour of Arabia, p 86, illustrations #9.31 and 9.33, he shows two such daggers. One is referred to come from Western India and the other is said to be from Bhuj, which is as close as you can get to Kutch

.
In the text on the same page the author writes, "The very best janabi and nimsha blades were imported into the Hadhramaut from Hyderabad where they were made and were simply referred to as 'Haidarabad'".
