So, was Jan Duijm's ship the Salamander?

At least up to November 1652, the Zeeland captain Jan Duijm commanded the ship Salamander, according to what Carl Stapel found. Carl wondered if this was the same ship that Pieter Marcuszoon commanded. In a list dated 17 August 1653, from Witte de With's journal, Pieter Marcuszoon is shown to command a ship of the Admiralty of Zeeland with 34 guns and a crew of 130 men. In October, a list with ship names gives the name of his ship as Salamander. This was probably the same ship as August, as a list from September 1653 gives his ship the same armament and crew.
