w. Piedmont, Sweet Cap, Sovereign, El Principe
de gales, Old Mill, and the brown Hindu.
In the 350 series no other brands issue it,
and it is dropped early from production,
possibly in 1909.
My thoughts are its a time related issue
because it is likely it was issued for a
longer period of time in the 150 series
than in the 350 series.
If that is the case, a Sovereign 350 series
green background Cobb would be a very difficult
card to acquire for example.
