This tunic is part of the service uniform of William Stewart Lochhead. Lochhead was born in Dunedin in 1880, trained as an engineer and served as a signaller during the South African War. After the war he was involved in mining operations in Nigeria and Brazil before joining up again during World War I. He served in engineering units before the Navy. Eventually Lochhead appears to have settled down. He fathered three children with his wife Lillian and spent the last years of his life living in New Plymouth. He died in May 1957.
