Here are some shots of the watermark on the telegraph stamp I posted the other day. As mentioned above, the crown does not resemble the two watermark crowns shown. There is what I will call 'scalloping' on the outside curves (I've tried to hi-lite them).
So don't know if there's another watermark listed that this may fall under.

So let me thank Joy Daschaudhuri for the amazing information that has been posted here. I'm sure other students of Indian philately will benefit from the knowledge imparted.
...And about that post last year? Sorry dude, didn't see it. Lost track of the post, got side tracked by life, I don't know. It wasn't personal, don't beat your head against a wall.
All I can say is, they're just pieces of paper. Your knowledge is an asset to this forum, and we are all the better philatelists for what you give us. But sometimes, ya gotta just let it go.
