The florar pattern was available on those drums from 1926-1928 with the scroll pattern running up to 1925 and the 10 point floral pattern starting in 1929. I see three different 12 leaf patterns in my books, one with a thick line in the leaves, one with a thin line and one with no line at all. May there is one pattern for each year of availability?
Anyone care to chime in on my theory there.
