I was reading Dr. Elias' book, Schetsen uit de Geschiedenis van ons Zeewezen, Vol.V, note 6 on page 59. This note mentions two lists of ships for the Admiralty of Rotterdam. One is dated 27 September 1652 and the other is dated 18 November 1652. Apparently, these discuss the armament that was carried by Witte de With's ship, the Prinses Louise. In September 1652, the Prinses Louise carried 36 guns. By November, it was over-armed with 46 guns! Tne note says that this was four guns fewer than was carried by the much larger Brederode. The actual reference is from an obsolete indexing system at the archive, but it says: "Hare Hoogh Mogende, van 27 Sept. en 18 Nov. 1652, L.A. (Lands Archief?) 5539 V. I have the list for 26 February 1652, and it is priceless. This should be of similar vallue.
