The Dutch ship Vrijheid on 21 June 1653

I have the inventory for the Dutch warship Vrijheid, dated 21 June 1653. The thing that caught my eye was that I had thought that the Vrijheid carried 52 guns on that date, but I was wrong, the Vrijheid had 50 guns:

Lower Deck
4-24pdr
18-12pdr

Upper Deck
4-12pdr
20-8pdr
2-6pdr
2-3pdr
