Admiralty of the Noorderkwartier 1648-1654

We know somewhat more about the ships of the Admiralty of the Noorderkwartier in 1654, but for completeness, I think that we need to consider the entire period from the peace treaty with Spain in 1648 up through the end of the First Anglo-Dutch War. I am fairly familiar with what is in the Nationaal Archief from this period and I would agree that we do not know a very complete story about this admiralty during 1648-1654. We have hypothesized that either there is more in the Westfries Archief in Hoorn, or else the rest of the information is lost. I hope that it exists somewhere, because we have relatively good information about the other admiralties during this period.
