I had not picked up on the last item that I hope to be receiving soon: "the account of the directors of Veere concerning the extraordinary equipment of the warship 'Wapen van der Vere'." I suspect that the name of Jan Olivierszoon's ship was
Wapen van der Vere, given this, as he served the Veere Directors during the First Anglo-Dutch War. Perhaps there are even specifications and armament, if this is anything like what I have from the Amsterdam Directors.
