Ned Kelly's Helmet

This is Exhibit 2 in my Farm Gallery.
I wonder if it could be Ned Kelly's helmet?
Thanks for Derelict Sunday Marlieske.

Another quiet day on farm. Nice weather after 15mm rain last night in two brief but violent storms. 
Some more gardening done. 
The cloudiness in the pool is slowly clearing. 
I even spent half an hour reading my book. It's rare that I do that during the day. I'd never get anything else done once I started.
