A different list of Rotterdam ships in the Extraordinary Equipage

I have a document, a letter dated 28 July 1652 from Witte de With, that I received in early February 2007 that lists the Rotterdam ships that were funded by the 100 Ships of 1652 (the Extraordinary Equipage). This is interesting, because it is another list to compare to what we have seen from December 1652:

Adm Ship              Gun  Commander
R   Overijssel        22   Cornelis Engelen Silvergieter
R   Utrecht           22   Leendert Haexwant
R   Hollandia     24 or 26 Ernestus de Bertrij
R   Beer              24   Jan de Haes
R   Sphera Mundi      26   Reijnout Venhuijsen
R   Calmer Sleutel    24   Dirck Vijch
R   Maria             24   Quirijn van den Kerckhoff
R   Roscam            26   Christiaen Eldertszoon
