I keep seeing cases where the writers did not know the exact list of guns carried by ships

I received a photograph, in the last day, which explained part of a fuzzy photograph from several weeks ago. The out of focus photograph had gun lists for the Noorderkwartier hired ships Vergulde Schel and Peereboom, and the Enkhuizen Directors' ship Maecht van Enkhuizen. For the Vergulde Schel, there were 10-3 or 4pdr guns, while the Maecht van Enkhuizen had "4 small, bronze klokwijs guns", with no shot size specified.
