Nico Brinck agrees that the ship was almost certainly the Prins Maurits

I received mail from Nico Brinck, and he gave me a new drawing of an iron 12pdr cast in Sweden. The gun seems to have been 8ft-9in long and weighted 3208 lbs. The gun was cast by Finspong, in Sweden and was used by the Admiralty of Friesland. Nico said that the passage from Dr. Elias' book about the loss of Cornelis Taenman's ship was more solid evidence than what they had used to associate the Tobias with the gun and captain. The gun is marked with crossed anchors and "A I F" (Admiraliteit in Friesland). Dr. Elias wrote that the ship was the Prins Maurits. She was lost while fighting in the rear-guard at the Battle of Scheveningen. The ship was lost off the Maasbank, where they found the wreck.
