OK, so it looks like the earliest would be March 1931 for USA, add 3-4 months for Australia, so about June-July 1931 for Australia. Definitely fits in with 1930 models being sold into 1932 in Australia, somewhere near the end of the A before the newer B and V-8's. It certainly raised a few interests in our club from a few of us into these details, and certainly very rare, being a 1930 slant windshield, made and sold in mid to late 1931.
