Unusual WW2 Brodie Helmet Other Allied Issue.

A non-British issue WW2 Brodie Helmet, it needs a little research, but it is possibly South African, but to be honest, I Don't Know. It has a typical steel shell but a British style, leather liner and a US type chin strap. It is in very good condition but shows obvious signs of age and wear and it retains most of its original very light green / brown sand coloured paint.
