Australian Vintage Wheelbarrow

My mother's cousin's boys, in Australia.
This is the cousin she knew of as Sonny - but he was always known in Australia as Charlie, where he emigrated in the early 1920s. (His actual name was Edwin - how confusing is that?)
My mother never met him, just his sisters - Edna, Olive, and Ivy.
Sent to me by Erin (Earp) Hobson, my 2nd cousin, once removed. Her Dad, Brian, is pushing the wheelbarrow, and his brothers are Ian and Charlie.
