Indo Persian Helmet--top missing?

[naborow]

I don't know what you mean by coming out of India recently, but we personally have had it sitting around in a box with the other stuff for about 20 years.

the hole at the top is about 1 1/2 cm deep and 1/2 cm wide. Its interior is oxidized and crusty. there is a 1/2 cm deep tube which appears to have some threads.

based on the pictures on internet of 1903 Delhi durbar, I think there was no spike, as all of the photos and paintings of the procession show plumes.
