The Newfoundland Overseas Forestry Unit was a civilian organization and as far as I know (mostly from photos and a faint recollection of some stories told in the early 1960s by a former Newfie forester who used to work for my grandfather) did not wear uniforms logging. The badge seemed to be worn on the lapel of their civvy coats.
Whether those who served in the Home Guard wore the NOFU badge is another matter, but from the photos I've seen (mostly very grainy and not too clear) it doesn't appear so.
