Many weapons did, as we know, travel a lot, so the Mysore one, most likely is a traveller. I agree with you on Jaiwant Paul, and a few others no doubt, but the pictures are getting better and better the more books he publishes

The five rivets are likely to come from Bukhara or somewhere north, but I think the big rivets very likely come from Bukhara. I don’t know about any special watering used in the area, and the Moser collection has been packed away for some years now, so try to ask Rivkin, he may have the answer.
