Yes Pieter, very valid comment.
If the mouth inside is black, it might even qualify for doitsu showa????, especially in view of the fact that there are sumi on the head.
However, it has the typical Sanke features.
I notice that there are no sumi stripes in the pectoral fins which you could expect from a Doitsu Sanke.
I think this one must have caused some doubt amongst the benchers at the show.
